Question: what is dpsk advantages and disadvantages of psk?
Answer: Drawbacks or disadvantages of DPSK modulation ➨Probability of error or BER (Bit Error Rate) is higher in DPSK compare to BPSK. ➨Noise interference in DPSK is more. ➨DPSK modulation uses two successive bits for its reception. Hence error in first bit creates error in second bit and consecutively error propagates.
