RAKE RECEIVER IN CDMA ADAPTIVE ARRAY ANTENNA SYSTEM

摘要

The present invention relates to a next generation wireless relates to a baseband modem in a communication system, in particular the baseband signal processing section of the rake receiver in the base station system using an array antenna.; Transmitting the best signal by having the array antenna, receiving CDMA adaptive array antenna in a baseband signal processing section of the system through the RF to obtain the synchronization information is a search for the wireless transmission route from the multiple antenna signals quantized to a large power signal explorer and, the weight calculation in accordance with the incident direction of the weight vector calculator and a terminal signal is applied to terminal performs despreading with a spreading code of a transmission signal by calculating the orientation of each arriving path of the correlator, the terminal signal to separate physical channels weight is tiled, CDMA adaptive array consisting of a channel estimator for estimating a signal distortion caused in a wireless section, the combiner summing the channel compensator, the signal demodulated value by arriving path of the terminal signals to correct the distortion by using a channel estimation value for a rake receiver of the antenna system.
