PROBLEM TO BE SOLVED: To enhance the communication quality in a semi-duplex communication system. SOLUTION: A radio unit 44 of a transmitter-receiver of one station transmits a quality estimate signal 3g having been stored in advance in a quality estimate memory 37 in a 1st communication timing to a transmitter-receiver of an opposite station, the transmitter-receiver of the opposite station allows a calculation section 51 to calculate distortion on the basis of the received quality estimate signal and a quality estimate signal having been stored in advance in its quality estimate signal memory 50 and same with the received quality estimate signal and a generator 52 generates a distortion correction information signal to cancel the distortion. The opposite station transmits the distortion correction information signal to its own station and a correction device 42 of its own station corrects the transmission data signal and transmits the corrected signal based on the distortion correction information signal. |
