Hi,I am trying to design the timing recovery loop in the qam demodulator.If i have finished the algorithm design of the loop,then how can i verify my design in the matlab/simulink?How can i get the proper input I/Q data and the right output data,which can be used to verify my verilog implementation? Thanks!
You can go to the simulink and in the analog modulation section there will be qam. Well i have tried to do OFDM in matlab but i could not find it.. that's the exact model for OFDM is not readily available. go for the simulink tutorial book given by MATLAB itself!
hi all , i need block diagrams for simulink in matlab for the modulators and demodulators for 8-qam and QPSK thanks
Dear Bro! I have a problem with my model: i can't use any qam block in simulink for DSK6416, because Link for CCS don't support any modulation block of Communication Blocksets. How can replace qam block in my model? Thanks!
Hi there, I need to design a QPSK and qam receiver in simulink based on the provided transmitter design. It is meant to simulate transmission of data through a wireless channel. In this case an image is the data to be transmitted and my receiver has to receive the data with the highest possible efficiency. This is done by comparing the sent and

I am working in coded OFDM as well.....seems like your project is not easy. Are you a student in you master degree?You need to do it in m-files or simulink?
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)
you can search in matlab suing qam both m-function and simulink can use

Hi, I'm creating a simulator of the physical layer of DVB-H, and I'm doing tests over a Rician multipath channel concatenated with an AWGN channel. My problem deals with the simulink's AWGN Channel block. One of the parameters I have to set if I want to generate the noise based on Eb/No is the "number of bits per symbol". I'm using 16qam, so
Hello, I have modelled a system (in Mathlab/simulink environment) based on qam- CCK (complementary code keying) modulation. As you know CCK provides 11MBs data rate for wireless communication systems using QPSK modulation. I had an idea and tried it in Mathlab/simulink environment. I thought that if I use qam instead (...)

That topic explains how to register and download the simulink models. There is including model with 16 qam and CMA helpful for you, but not completely ready for the outcome of your problem.
Hi, first, I'm not english so I'm sorry for my poor language. My project is to make a model of baseband OFDM transmission without FFT/IFFT on simulink. So on the first side I take a bernoulli binary and Rectangular 4-qam to build complex symbols and on the second side I make my 3 complex sine with frequencies . Then I multiply si
Hello folks, just discovered this valuable forum through google. I searched the forum regarding Rayleigh channel modeling and all I found was matlab m files, so I'm chancing it and hope you might be able to help. I'm currently designing a simulink model for adaptive digital audio transmission, in an AWGN channel it works fine, but I have tr
Hi friends!, I am involved with software defined radio project. hence i need to design the FPGA with all possible modulation esp for students study purpose. Now that i have seen many websites for a proper knowledge of how to design 16-qam or 32-qam, but i couldn't find such detailed diagram or atleast block diagram anywhere in the internet :cry: We
Hi, I'm creating a digital communication system simulink model based on 64-qam. Currently the model needs to have the following block: SOURCE source block (I'm using a benoulli binary generator for this) TRANSMITTER: channel coding block (I'm using an FEC coder, consisting of the Convolutional Encoder) modulator (I'm using the Rectang
Hello! How can I synchronize acquired analog signals using Data Acquisition Toolbox in simulink? I'm doing a 16-qam modem and using the analog input and analog blocks output, using them as a receiver and transmitter with two computers, this is possible using the PC's sound card? Can someone help me? Thank's!
Here is 4qam basic modem model made with Matlab 2009b simulink. You can easily add 4 more phases in the TX1D/RX2D lists. All of used ones are 30deg shifted now. The signal filtering is made using raised cosine filter, so You can remove them if not needed. If the model doesn't work (Altera DSP builder error or smth..), select all items, copy and pa
Our circuit for 16-qam MODEM with DPLL as its demodulator in simulink is showing a number of errors.Please help us with the circuit design.
I am simulating the physical layer of WIMAX on simulink using a 16 qam only. There is problem with my module that appears as different states between the input and the output. I need help with the error in the simulation. the simulink model is attached. thanks for trying to help.
What is the error you are getting? If you can upload your simulink file ( .mdl file) it would help me finding the error.
Hi, The simplest is to use simulink to generate WCDMA. Other options include specific Matlab, Octave code. Further there are also C++ codes. All depends on your budget and time limitations. All of them support offline as well as quasi-real-time analysis

Hi all, I need to make a 128 qam demodulator, but I have some difficulties on RF input stage. Can someone suggest me some tips to make a good downconverter or tips to achieve a maximum linearity ?? (2.4 GHz -> 70 MHz) Many thanks in advance. Sirio.
Hi. Please consider two constellations of for example 16-qam :an uniform and a nonuniform (inwhich all of distances aren't equal) . As the output we allocate 00, 01, 10 and 11 to the I axe respectively from the left and the same to the Q axe from the down and we send 4 bits.This allocation is the same for both systems. So what is the differe
Is there any one who has used "LMS Equlizer" block available in matlab simulink? Does any body knows its internal architecture. Recently, I searched a lot about channel equalization techniques when you are using one of QPSK , GMSK, ... modulations, But I did not fing any thing about how, we should design, a for example, adaptive channel equalizer

One possible way is to use predefined simulink blockset as provide by tools such as Xilinx System Generator. Each primitive in the blockset has a corresponding hardware implementation and a simulation model. Using high-level synthesis tools like AccelChip you can synthesize HW from your MATLAB code.
