A METHOD FOR CONFIGURING AND DEMODULATING MULTIPLE SCRAMBLED CODES IN CDMA SYSTEM

摘要

A method for configuring and demodulating multiple scrambled codes in CDMA system, increases the system capacity by configuring multiple scrambled codes in multiple antennas system, the method comprises the following steps: configures multiple scrambled codes for each cell, the generating method and amount of spread codes for each cell is consistent with that in conventional way; the generating method for subscriber training sequence is consistent with the provision of current TD protocol, only different in shortening the width of the channel pulse response window for each subscriber when probably causing multiple scrambled codes. The method according to the invention takes full advantage of any multiple antennas system, especially makes use of the space-division (SDMA) character resulting from multiple antennas in TD-SCDMA system, adopts a particular method for configuring wireless resource and the demodulating method thereof, reallocates the scrambled code resource, uses multiple scrambled codes in each cell, thereby greatly improves the system capacity, increases the availability of frequency band, and saves the frequency resource. .
