Abstract :
In this paper, the differential encoding and detection methods in single-carrier frequency-division multiple access (SC-FDMA) systems are investigated. Like in OFDM systems, the differential encoding can be performed in time-domain or frequency-domain in SC-FDMA systems. Also, we can use differential encoding before or after the discrete Fourier transform (DFT) process. Thus the detail design of transmitter with each of the four differential coding methods and the corresponding detection methods is considered and analyzed.
