Hello all,
I am working on sparse channels with frequency domain equalization (FDE), where the transmission is block-based, which is very similar in structure to OFDM, where each frame begins with a CP. The problem in sparse channels is that the channel impulse response (CIR) is very long, while just a small number of taps are non-zero. So, is there any paper dealing with this issue in particular? i.e.: is there any efficient method to reduce the number of CP length, and make it proportional to the number of non-zero taps instead of the number of taps?
Thanks
