摘要： In the hardware-efficient demodulator for a CDMA adaptive antenna array mechanism of a mobile radio communication system, a correlators bank receives digital baseband signals received through an antenna array of a base station and computes correlation values with a local code sequence. A beamformer receives the digital baseband signals and the correlation values from the correlators bank and calculates beamforming weight vectors. A searchers bank receives the digital baseband signals and calculates an initial acquisition and reliable timing information for a multipath search by a common work with the beamformer, which uses a beamforming algorithm. A beamforming complex multiplier for a finger performs a complex multiplication for the beamforming weight vectors and the digital baseband signals, and sums up them. A finger bank receives output signals from the beamforming complex multiplier, executes a code tracking for an alignment between a transmission code and a phase by each multipath on the basis of the multipath search timing information to then provide the timing information of the multipath tracking to the correlators bank, and outputs signals of dispreaded multipath through a time alignment based on each path. A multipath combiner performs a multipath combination for the output signals of the finger bank on a time base and outputting it.
