WebDPSK 1) Draw the block diagram of a DPSK transmitter, if the following binary sequence 1100100010 is applied to the DPSK transmitter that you have drawn sketch the resulting waveform at the transmitter output. Assume the reference bit is 1. 2) Mention one of the disadvantages of the DPSK receiver. M-ary PSK Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by changing the phase of the carrier wave. As mentioned for BPSK and QPSK there is an ambiguity of phase if the constellation is rotated by some effect in the communications channel through which the signal passes. This problem can be overcome by using the data to change rather than set th…
