Abstract
An apparatus and method for synchronizing the transmission of uplink signals and reception of downlink signals by a terminal in a mobile communication system is disclosed, the apparatus and method allowing the terminal itself to adaptively compensate for deflection generated in synchronization of the transmission channel and to recover a synchronization error of the transmission channel without re-setting communications with the base station. A feedback path is formed between a transmitting unit, a receiving unit and a processing unit to facilitate frequently checking the synchronization between uplink and downlink timeslots by generating a reference signal input to the transmitting unit and comparing a signal received from the receiving unit. The channel synchronization apparatus and method may be adapted for a terminal using a software-based modem or a hardware-based modem.
