 01 Apr 2006 4:53 Help!! Design of an OFDM channel w/ M-QAM and FEC conv |
|
|
|
Need to simulate a wireless channel with an M-ary QAM scheme for frames/audio or both. The suggested architechute is as follows
Data - Modulation - FEC coding - filter - istropic antenna - Channel+Noise - antenna - filter - FEC decoding - Demodulation - Dataout.
M>32 for QAM
BW ~ 6Mhz
If anybody has already simulated such a channel or a similar channel in Matlab, could you pls upload or forward (ars0242(at)yahoo.com) ur code pls, it would be a great help.
Thanks

I have created a model using simulink simulating what you have stated but not the antenna.
what i suggest is that you choose a system (wi-fi, DVB, etc...) and look into the standard and start creating your model.

| 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?
