Hi I am working on an audio file in simulink .I have given the A-law compressor and expander for source coding and used digital pass band modulation and demodulation and unbuffer and buffer but still Im not getting an output without noise. Im unable to find out where is the mistake and how to rectify it. Please help me to solve this.
Dear all, I would like to transmit an Audio file over the Air and Receive at other end... for this Purpose, I just took 1. a simple audio file from computer => Up-sampled to 8 KHz and then=> Re-sampled to the device frequency (USRP i.e 200 Khz) => FM modulated and transmitted via USRP, 2. at RX Usrp, downsampled, FM demodulation and FIR decimat
hello can someone explain how to implement 64 ary orthogonal walsh demodulation in simulink. i need it in cdma reverse link implementation. an urgent reply would be appreciated. 8-)
I want matlab code for demodulation in BFSK...please ASAP.... It is very simple to implement BFSK De-modulator you have to make two filters and diode detectors. What you can do implement the design on simulink and generate its code.
Hello, Can you suggest me how can we demodulate the DQPSK signal in simulink, using the Xilinx blockset. I am implementing in FPGA, hence I need to use only the xilinx blockset. Any pointers for the tutorial would be helpful as well. Regards Kiran
i have to narrow band pm modulation and demodulation is simulink. i have done modulation and for demodualtion i am doing envelope detection using hilbert transform. but its giving error .can any one please rectify this error. i am attaching the simulink file.
Hello. I have a model of FSK modulation and demodulation in simulnk Matlab. But I do not have the parameters of the blocks. I am particularly interested in what values to set the sine Wave2, 3, 5 and also in discrete time integrators. This I need for the exam. I pray for help. Thanks p.s. I placed formed MATLAB simulink model (fskmatlab.rar)

see this post it has most of the modulation types by simulink
for example, seaching for simulink SSB modulation will give you several hits.
there are a lot of such simulink models in this link just search it
I need matlab codes for bpsk modulation and demodulation.please help.urgent.
plz share simulink model of a digital tanlock loop.. tryin to implement it on fpga for demodulation.. there's hardly any literature that i could find on this topic.. help me with any content or suggestions.. Thank U...
Hi, If you have some simulink models such as AM, FM, BPSK, FSK modulators and demodulators, please upload them or email them to me. Best Regards, Ahmed
hi to all, i have to implement delay lock loop in matlab/simulink for fm demodulation.if you people can please guide me from where to start. and how to model it. i ll really apreciate your help thanks alot!
Hi u can use communication tab in simulink and FM. MATLAB HELP is the best ref for MATLAB use. BR
Can i get a simulink or matlab code for FM modulation demodulation with some explanation. If anyone has it i'll really appreciate if they provide it thanks
you can just use matlab tool boxes and simulink to accomplish this. BRM
im doing a project bps modulation n demodulation in matlab coding using simulink.... can any one help me how to get started in this... plz send me if u have coding for that... thanks in advance...
Hi, Is there anybody who have worked with simulink embedded target for BPSK demodulation. I want to know which embedded card to use, what are the steps of the applications.... I would be glad if you share your experiences in the subject.
There are PLL model in the simulink library. Use it directly.
