Consider a digital communication system employing the waveforms
here hTx(t) is a rectangular pulse with support [0, T ), T = 1 ms and amplitude A = 1 V. Assume that the channel introduces a 20 dB attenuation and an AWGN noise with PSD Determine:
a) The system block diagram, the waveform constellation at the decision point and the corresponding decision regions.
b) The system error probability.
c) The system error probability in the presence of an additional periodic disturbance at the receiver input given by
