Abstract
A communication system of a time division multiple access method in which transmission data are transmitted in a unit of a frame having a predetermined number of symbols in which a pilot symbol is periodically inserted in a series of data symbols for compensation of fading distortion and a carrier is reset at each frame. A phase correction circuit for correcting phase variation due to the reset of carrier phase at each frame is provided. When pilot symbols except a frame in which fading distortion is to be compensated are used in a receiving side, the pilot symbols corrected by the phase correction circuit can be selected to thereby compensate fading distortion exactly regardless of an insertion position of pilot symbols in the frame even by using the interpolation method.
