Q3) In coherent schemes, a small pilot is added for synchronization. Because the pilot does not carry information, it causes degradation in Pb. Consider Coherent PSK. Assume that the following two pulses of duration Tb is used: where is the pilot. Find the error probability when the channel is additive white Gaussian noise with power spectral density of N/2. Hint: Use the general expression for the error rate in binary signaling. p(t) = A (1 – B2)cos(wet) + AB sin(wet)
