Abstract:
1. A communication device for receiving transmitted orthogonal frequency division multiplexed (OFDM) signals in a wireless communication system, the communication device comprising: means for receiving a plurality of OFDM signals transmitted by a plurality of transmission antennas via a plurality of transmission channels in said wireless communication system, wherein each of said plurality of OFDM signals comprises a plurality of subcarrier signals; means for performing channel estimation processing and decoding processing on said plurality of received OFDM signals; and means for weighting said plurality of received OFDM signals by weight vectors chosen to improve a performance of said plurality of received OFDM signals expressed by elements of said weight vectors and channel vectors, wherein the performance of said plurality of received OFDM signals is expressed by the elements of said weight vectors and a Hermitian matrix having elements of channel vectors, and the means for weighting chooses weight vectors based on an Eigenvector of an Eigenvalue of said Hermitian matrix.
