Radio communication system capable of carrying out a data transmission with a high reliability

摘要

A radio communication system comprises a master station for carrying out a bidirectional communication between the master station and a slave station in time division multiple access. The master station comprises comparator circuit for producing a phase difference data between a slave frame signal of a of a slave transmission signal and a master frame signal of a master transmission signal. A first detecting circuit produces a first detection signal representative of whether or not a field strength level is less than a predetermined level. The phase difference data and the first detection signal are transmitted to the slave station. The slave station comprises a delay circuit for give a delay to the slave transmission signal in accordance with a given phase difference. A supplying section is responsive to the first detection signal to selectively supply the delay means with the phase difference data as the given phase difference.
