Hi all, I need some help here... I am currently doing a project regarding ofdm wireless transmission using fpga. Is that possible to interface the cellular front end module (such as SST12LF02, MAX2335.. etc) with a fpga Board? Any idea?

hi mkrish, I'm doing a project on lifting based 3d dwt for image compression so can you share matlab/simulink/verilog code for 2D/3D-Dwt based ofdm(input is an RGB image).. help the needfull.. Thankyou in Advance.
Do you mean you generated ofdm signal using fpga and used on-board DAC to convert digital signal to analogue signal. And plot the spectrum using spectrum analyzer? Did you add Q-component and I-component signals together?
Dear Friends, Kindly, I just started the Verilog learning to implement my ofdm system. As a first step, I need to implement a simple QAM Transmitter and receiver as a start point for me. I do not know how to send data to the system from my pc and how to collect it at the pc again from the fpga board!! Would somebody advise me please? I need a
No idea if this is exactly what you want, but it was the first hit on Google: ofdm modem :: Overview :: OpenCores
Hi, DDs is such a great idea, its briliant for ofdm. I once tested a 100Mhz with VirtexIV-LX, from Analog devices in current mode, but the thing is that for higher frequencies there are only video decoders, you can use them for other purposes, yes..... but what's your application? Texas Instrument has very goode codecs. Regards.
hello we're working on out graduation project titled "An fpga design of ofdm modulator for LTE networks" using XILINX's SYSTEM GENERATOR to download the code to the fpga chip "SPARTAN 3AN" there must be some sort of comparison in the results chapter and we still cant decide what the reference model "ideal simulation" should be? some (...)
im asked to design a baseband tranceiver as a project for the course "wireless communication system" . so i picked the ofdm tranceiver, and i want to design it using verilog and download it in cyclonII fpga. could u please help me and tell me how to start doing that and what is the circiut diagram fo such a model....
I'd probably start with learning the basics of ofdm...
hi iam working on my graduation project which is design and implment ofdm transmitter and reciver using 8 points IFFT/FFT on fpga. Now am stuck on the DQPSK mapper i can't figure out how to write the vhdl code . if anyone can help with the code i will appreciate it so much. please any tips avaliable?

Hello all, I want to carry out an experiment which consists of "operating" a digital TV channel in the UHF band in order to remove/add contents. The DTV channel is 64QAM, 8MHz bandwidth, 8K subcarriers. After de decoder, the DSP/fpga will deal with the streams, and then will be encoded again: Will anyone expect an appreciable delayed effect in
Can anybody provide me reliable links about fpga VHDL implementation of ofdm transceiver ? Both baseband(fpga) and RF-end (Non-fpga)implementation desired. Main blocks for implementation are FFT/IFFT,scrambler/de-scrambler,mapper/de-mapper,cyclic-prefix add/remove,coder/decoder,bit interleaver/de-interleaver, etc. (...)
I implement ofdm transmitter and receiver on fpga kit (Tx and Rx on same kit). The data is transmitted through wireless channel. I do channel estimation. But should I do Synchronization? (or not due to not using separate kits Tx & Rx). Please, answer me as fast as possible...
Hi we too are in the same problem. pls go thru some of the ref designs by HARDWARE IMPLEMENTATION OF ofdm TRASNMITTER AND RECEIVER USING fpga by SHAHBAZ ABBASI (google it) This in verilog
any one knowing how to implement ofdm on fpga ???
Hi dear Ahmad you could you xilinx cores for the FFT and cyclic prefix for the ofdm system, also you could use PN generatot cores of CDMA. I used spartan 3A , it was good and cheap. if you want more details tell me.
hi.. i m doing graduation and my final year project is simulation of ofdm. can anyone help me.... how actually IFFT works in ofdm ?
ofdm modulation/demodulation is implemented by FFT/IFFT, so what you need is to implement a fft ip core. Xilinx FFT 7.0 may be the choice.
Hi; I am working on "fpga based ofdm Modulator" Project using SPARTAN 3E (Xilinx) fpga card. Is there any one who worked on it (fpga, ofdm)........? ...........i need help about using fpga and its coding using VHDL...
I would like to test some of my algorithms(convolutional code, ofdm, modulation, mimo, equalization, channel estimation and etc) in real world. I wonder if anyone can tell me whether there is any development kit that has RF module and DSP processor/ fpga. So, I can edit and modify my algorithm on board and make use of the RF module to transmit sign

Hi all for a specific project I have to stimate how much ram do I need for ofdm modulation and demodulation (WiMax) to impliment it on fpga chip, however I do not know how I can estimate it. I have this information: FFT : 1024 BW: 10Mhz Symbol number: 46: 1- Uplink: 15=12data+3 parity & bit per symbol: 560 2-Downlink: 31 = 28data+3parity & 7
Hardware Implementation of ofdm on fpga
implimentation of ofdm system using fpga
Was dr... I have over one year experience of working in verilog and fpga Kits (Both Quartus and ISE) and have done several projects including one major project of designing ofdm PHY... I can teach you through the initial stage of entering into the design work. I also have extensive computer based fpga material... Let me know if you (...)
Hi! I have simulated an ofdm communication model in simulink and I have used an AWGN channel to simulate the wireless media. Now I would like to implement this model in real world and I'm planing to transmit the signal, generated by MATLAB, through external hardware unit/s. But the problem is that i don't know how to physically transmit the MATL
Hi all I want to implement ORTHOGNAL FREQUENCY DIVISION MULTIPLEXING on fpga. Right now i have no ideo how to start? Plz if somebody can give me any roadmap to follow. What are the prerequsites which i will have to learn. Any comments, suggestions; Most welcome:D
ROUTER IMPLEMENTAION,ofdm ,BLUETOOTH ETC CAN BE SELECTED.
i want to make a thesis on MIMO ofdm but i think i need a suggestion for a more specific subject i've heard something about fpga or a SIMULINK/MATLAB simulation i have plenty experience working on both but i need something more specific :)
hi frz iam doing my project in MB-ofdm UWB receiver. i do want to implement the 128 point fft block.i have decided to do using 8 parralel radix 2 butterflies. i dont know hw to start it.can any one help me with the VHDL CODINGS FOR IT OR PROVIDE ANY SUGGESTIONS. iam also confused that whether this is MIMO or SISO system. frz plz lend me ur sugge

i need verilog code for implementing ofdm on fpga.
ofdm on fpga I'm working on the implementation.
Plz send me material related to fpga BASED ofdm MODEM thanks
Do an fpga design that implements an ofdm encoder/decoder. You can say that you aren't going to worry about the wireless channel, and instead just send the ofdm signal through a wire, back to your receiver.
Hello everybody, I'm implementing a software radio that use ofdm. The first part of my project is to design and simulate the transmiter/receiber in Simulink. My question is in the modulation part. Should I use as many QAM modules (PSK, PAM, or the desired modulation module)
I think Implementation of Digital modulator and demodulator on DSP or fpga will be a good project, for example u can implement ofdm on DSP .
Hello everyone, I'd like to have your opinion in a very critical issue in my graduation project which is the implementation of MIMO ofdm Tx & Rx (using fpga & interfacing...) there's an idea to do the modulation part (ofdm) using SDR having a small microprocessor & writing code to be its operating system then writing the (...)
Hi everyone, Does anybody here knows how to calculate the RMS voltage of an ofdm signal? suppose you output an ofdm signal from an DAC and want to measure what is the RMS value of it. Is the measurement can be done by scope? Can anyone here give me a reference to article/site that explains the issue. Regards
Hi, guys Who knows how to implement a ofdm channal estimation algorithm, for instance, LS and MMSE, on a fpga devices. Could you please give me some reference design or academic papers? Cheers,
hi, i have uploaded a good tutorial on ofdm. I hope it will help u in understanding the basics of ofdm technology.
Hi there, What part of an ofdm Transceiver are you going to design. Designing the whole chain is quite overwhelming and not realistic for a student project. If you could givee us more specifically what the objective of your project is, it would be easier to comment. REgards - TS
