Radio communication system, transmitter and receiver therefor

摘要

In a mobile radio communication system, a transmitter of a base station transmits broadcast information to receivers of mobile stations in the form of frames. The transmitter produces a long frame composed of a plurality of frames each including a first bit sequence and part of the broadcast information following the first bit sequence, and a second bit sequence located at the head of the long frame. Each of the first bit sequences and the second bit sequence is used for establishing synchronization between the transmitter and each of the receivers. Upon receipt of the long frame from the transmitter, the receiver establishes synchronization of the long frame based on the foregoing second bit sequence.
