Orthogonal frequency division multiplex processing method in multi antenna system, involves summing up I/Q values weighted with channel correction values

摘要

The channel correction values or confidence values for every carrier of orthogonal frequency division multiplex (OFDM) signals are determined in reception channels. The I/Q values of every individual carrier of OFDM signals are derived in OFDM demodulators (D1/m1-Dn/mn) and weighted with the channel correction values or confidence values. The weighted I/Q values are then summed up.
