Abstract:
1. A process for processing OFDM-signals, comprising the steps of: receiving substantially simultaneously the OFDM-signals by a multi-antenna system with two or more corresponding separate receiving channels; in each separate receiving channel, obtaining the I/Q-values of each individual carrier of the OFDM-signals and determining channel correction values or confidence values from pilots for each individual carrier of the OFDM-signals; deriving weighting factors from the channel correction or confidence values for each I/Q-value of each individual carrier and each separate receiving channel, by which weighting factors the I/Q-values of each individual carrier of the OFDM-signals obtained in an OFDM-demodulator are weighted such that I/Q-values of carriers received at a low level are weighted low and I/Q-values of carriers received at a high level are weighted high; and adding the weighted I/Q-values and dividing the added weighted I/Q-values by the number of all the weighting factors.
