Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a code division multiple access (CDMA) communication system which improves quality of a received signal further without raising a transmission power level.

SOLUTION: A method to receive a traffic signal in the code division multiple access communication system includes following methods. A signal is received through a shared spectrum. A sample is generated by sampling the received signal. A window is generated by delaying the sample. Here the window has the samples with equal time span. The samples are despread and weight about each despread window sample is determined using adaptive algorithm. Here the adaptive algorithm provides optimum weight determination about each of a plurality of despread components. The received signal is weighted using the determined weight. The weighted received-signal is despread using a traffic code. The system transmits a traffic signal through the shared spectrum and the traffic signal has a related signal.
