Question: what are advantages and disadvantages of dpsk?
Answer: ADVANTAGES OF DPSK: 1) DPSK does not need carrier at its receiver. Hence the complicated circuitry for generation of local carrier is avoided. 2) The bandwidth requirement of DPSK is reduced compared to that of BPSK. DISADVANTAGES: 1) The probability of error or bit error rate of DPSK is higher than that of BPSK.
