Simulation :
Repeat the above channel equalization problem for the following cases:
The channel is no longer as given by the cosine function. But, now let the channel be modeled by an FIR filter of length 10, and each FIR coefficient be of unit magnitude. This way we will be considering the performance of the equalizer under a narrow band channel
