Abstract
A communication device for receiving transmitted orthogonal frequency division multiplexed (OFDM) signals in a wireless communication system. The device includes a plurality of antenna elements to receive a plurality of OFDM signals transmitted from a transmitter via a plurality of transmission channels. The device performs channel estimation processing and decoding processing on the plurality of received OFDM signals, and weights the plurality of received OFDM signals by weight vectors chosen to improve a performance of the plurality of received OFDM signals.
