Hello everyone. I'm building a MIMO-OFDM simulator. Can I have some discussion with anyone interested in this,please? For example, I'm buildiing a 4-by-4 MIMO-OFDM simulator. Then, what is the best way I can verify the BER of my MIMO-OFDM simulator? Since I use 64-PSK, I assumed that, if I adopt a Gaussian channel for MIMO-OFDM with 64-PSK, then the BER will be the same as 64-PSK in AWGN...

I am currently doing a simulation of OFDM in Simulink to be later used in a TI DSP. There are a few demos in Simulink which involves OFDM which i play around to familiarise with the blocks before i build my own model. There is one demo in Simulink called [b]HiperLan2[/b] which involves OFDM. What i'm trying to do now is to display the output afte

Good day everyone. I am currently doing my thesis on OFDM and my supervisor wants me to simulate continuous-time OFDM (i.e without using FFT). I've been able to simulate it using FFT but I have been unsuccessful in simulating the continuous-time OFDM. I would really appreciate it if anyone could help me out with the code. Thanks

Hello, I am simulating OFDM transmission over a Fading Channel in Matlab (using the 2009a version) at my university I am concatenating 100 OFDM symbols, where one symbol has 80 samples (64 subcarriers and 16 cyclic prefix). I create a Rayleigh fading channel object and filter my serial stream of OFDM symbols with the fading channel. Now, the problem is that I want each OFDM symbol be ...
