Right now what i am doing is, i am extracting my pilots before AWGN and estimating the channel at receiver. But i wonder if there is some other way to obtain perfect CSI? Any hints and suggestions would be a great help. Thanks
EVA channel model for MIMO ... Each link between Tx antenna and Rx antennas are EVA Rayleigh faded.
I wonder, what pathgain output of MIMO channel block in simulink? I am trying to play with pathgains output of MIMO channel block in simulink but still i am unable ot equalize my signal at the receiver. Any suggestions
You can use the OSTBC blocks which include the encoder and combiner. The combiner actually does the CSI of the path gains of the MIMO channel. You will not need to include pilots in that case.
Thanks for the answer. Unfortunately, my system requirement doesnt allow me to use OSTBC. I am using frequency domain equalization (FDE) for that i need ideal frequency response.
Could you describe in detail? I am sorry if i am not getting your idea here ...
Which fading distribution are you using in the MIMO channel? Normally, for any Fading channel, you need to include an equalizer to equalize the gains as it is a dispersive channel and this degrades the system a lot, resulting a BER of 0.5. You can learn more about equalizer on Mathworks. Hope I've enlightened you a bit. Regards.
