<p>A method of performing data equalization in a communication receiver with transmit and receive diversity includes (a) for each i-th receiver antenna and j-th transmitter antenna, calculating a channel response matrix Hi,j from multi-path channel estimates, (b) each i-th receiver antenna, calculating a channel gain matrix Gi from the channel response matrices Hi,j and a scalar noise factorβ, (c) calculating the middle column c0 of Gi−1, (d) calculating a filter coefficient vector wi,j from the middle column c0 of Gi−1 of and the Hermitian transpose Hi,jH of the corresponding channel response matrices Hi,j, (e) filtering input data ri received at each i-th receiver antenna with the corresponding filter coefficient vectors wi,j, (f) despreading the filtered input data from each i-th receiver antenna, (g) applying phase compensation to the despread data, and (h) combining the despread data from all antennas to obtain received equalized data.</p> |
