CDMA WIRELESS COMMUNICATION SYSTEM AND METHOD THEREOF

摘要

PURPOSE: A Code Division Multiple Access(CDMA) wireless communication system is provided to be strong to a fading and a shadowing and to reducing a guard time and to expand a cell diameter in a Time Division Duplex(TDD) system. CONSTITUTION: A CDMA wireless communication system is composed of a transferring device and a receiving device. The transferring device comprises: diffuse treating transferring data(101) by a diffusing unit(102); chip interleave treating the transferring data by a chip interleaving unit(107); modulating the interleaf signal in a modulator(103); amplifying the signal in a transferring amplifier(104); and radiating the signal from a transferring antenna(105). The receiving device comprises: detecting the signal received by a receiving antenna(111) in a detecting unit(112); and re-arranging the signal by a chip de-interleaving unit(117) through a reversed process of the transferring chip interleave. And a slot quality detecting unit(116) detects a slot quality for a rapid transferring electric power controlling unit(115) to generate a rapid transferring electric power controlling signal according to the detected result for transferring to a transferor. And the transferor establishes the rapid transferring electric power in a rapid transferring electric power establishing unit(106) in the basis of the controlling signal for controlling the amplifying rate in a transferring amplifier(104).
