Title:

WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2018/003112

Kind Code:

A1

Abstract:

In the present invention an amplitude-phase calculation unit (32) calculates information about a propagation path between a receiving station (2) and each transmitting station (1-1 - 1-N) at each communication time for each communication site, and calculates an amplitude-phase correction amount for a communication symbol sequence. An amplitude-phase adjustment unit (33) uses the amplitude-phase correction amount to adjust the amplitude and phase of the communication symbol sequence, and transmits this adjusted signal from each transmitting station (1-1 - 1-N). A timing control unit (22) of the receiving station (2) controls the reception timing on the basis of each communication time, and a receiving RF unit (23) converts, with the controlled reception timing, the signals from the transmitting stations (1-1 - 1-N) to a baseband, and calculates a received symbol sequence.
