DATA DEMODULATION FOR CDMA COMMUNICATION SYSTEM Russian patent published in 2008 - IPC H04B1/707 

Abstract RU 2337479 C2

FIELD: physics, communications.

SUBSTANCE: integral circuit performing data demodulation includes: convolution module performing input sample convolution and presentation of convoluted symbols for first code channel with first propagation factor; channel compensation module performing multiplication of convoluted symbols with channel estimates and presentation of demodulated symbols for the first code channel; and symbol coupler performing combination of demodulated symbol groups for the first code channel used to restore data symbols for second code channel with second propagation factor, which is integer multiplier of the first propagation factor.

EFFECT: increased efficiency of data demodulation.
