question about channel.py

Open WenBingo opened this issue 1 year ago • 1 comments

I would like to consult the 'channel.py -> Channel.forward ', where code of " output_real = batch_conv1d(signal_real, cof_real) - batch_conv1d(signal_imag, cof_imag) # (NxP)x(L+SMK-1) output_imag = batch_conv1d(signal_real, cof_imag) + batch_conv1d(signal_imag, cof_real) # (NxP)x(L+SMK-1) " Why is the code written here？

it is the time domain convolution between the ofdm signal and the channel response
