1.	For non coherent reception of PSK _____ is used.(a) Differential encoding(b) Decoding(c) Differential encoding & Decoding(d) None of the mentionedThe question was posed to me in semester exam.This interesting question is from M-ary Modulation and Amplifiers topic in section Modulation and Coding Trade-off of Digital Communications
Answer» CORRECT answer is (c) Differential encoding & DECODING Easiest explanation: For non coherent RECEPTION of PSK, differential encoding is USED at the transmitter and decoding is used at the receiver.
