A digital bandpass system is suitable for BPSK as well as FSK modulation. The coherent receiver used, has a detector with adaptable filter bandwidth. The data rate is equal to Rp = 230 kbit/sec. The white noise at the receiver input has a Gaussian amplitude distribution with a single-sided power spectral density No = 45 pW/Hz. = a. Preceive Number dBm Calculate the received power needed to achieve a bit error probability Pe=9*10-6 when BPSK modulation is used and the equivalent noise bandwidth of the detection filter is equal to 2.5*Rh. Preceive Number dBm b. Calculate the received power needed to achieve a bit error probability Pe=6*10-3 when FSK modulation is used and the equivalent noise bandwidth of the detection filter is equal to 4*Rp
