摘要： A transmitted OFDM signal is detected in a receiver of a wireless communication system. The receiver has at least two receiver branches, each comprising an antenna, a front end receiver, a Discrete Fourier Transform unit, and a channel estimator. The receiver further comprises a detector for detecting received data symbols. The method comprises the steps of determining a system bandwidth associated with the transmitted signal; comparing the determined system bandwidth with a predetermined value; determining, if the system bandwidth is lower than the predetermined value, channel estimates separately for each branch, and detecting received data symbols from the received signals and corresponding channel estimates; and calculating, if the system bandwidth is higher than the predetermined value, a weighted sum of signals from each branch, determining a combined channel estimate, and detecting received data symbols from the weighted sum and the combined channel estimate.
