METHOD FOR EXECUTING EQUALIZATION IN MC-CDMA (MULTI- CARRIER CODE DIVISION MULTIPLE ACCESS) RECEIVER AND MULTI- CARRIER CDMA RECEIVER OF MC-CDMA COMMUNICATION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a method for executing equalization by every carrier in an MC-CDMA (multi-carrier code division multiple access) receiver using less transmission resources. PSOLUTION: In this method, a symbol to be transmitted to the receiver is spread by a spreading system for over a plurality (N) of carriers, a signal to be received by the receiver is decomposed into a plurality of frequency components (rSB1/SB), relative power values are estimated 331 in each of the carriers, a plurality of equalization coefficients (qSB1/SB) are calculated 333 from the estimated relative power values of an equation (1) and the respective frequency components are multiplied (334SB0/SB,...334LSB-1/SB).
