Question

Represent the four waveforms as vectors using the basis functions. Plot the signal constellation. 14.17 A communication system is operating a coherent BPSK receiver at 5,000 bps. The amplitude of the received BPSK waveform is l mV. The noise N 10o W/Hz In one pectral density day, what is the number of expected errors assuming ower a -2 resistance as the load? 14.18 Repeat the above problem for a BASK receiver with (a) 100% modulation and (b) 50% modulation. Assume 1 mV is the peak received amplitude 14.19 Repeat the above problem for a BFSK receiver. Assume I mV is the peak received amplitude. 1.1.30 X7E

14.17 through 14.19. please help..and use 1.25kbps instead of the 5,000bps and 1.25 kHz of bandpass..thanks..
