A receiver in which computation is simplified can be obtained by using a common factor for filter coefficients of FIR filters corresponding to a plurality of transmitting antennas and by using only the middle column of an inverse matrix of a gain matrix when the common factor is computed.

Receiver

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 Hfrom multi-path channel estimates, (b) each i-th receiver antenna, calculating a channel gain matrix Gfrom the channel response matrices Hand a scalar noise factor &#x3b2;, (c) calculating the middle column cof G, (d) calculating a filter coefficient vector wfrom the middle column cof Gof and the Hermitian transpose Hof the corresponding channel response matrices H, (e) filtering input data rreceived at each i-th receiver antenna with the corresponding filter coefficient vectors w, (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.

Data equalisation in a communication receiver wth transmit and receive diversity

A method of cancelling interference induced by a coherent interference source in a spread spectrum receiver comprising the steps of: quantifying () first interference values induced by the coherent interference source (SCH) in symbols on a first spread spectrum physical channel (P-CCPCH; CPICH); calculating () second interference values induced by the coherent interference source in symbols on a second spread spectrum channel (DPCH) from the first interference values; and applying () a correction value, derived from the second interference values, to the symbols on the second spread spectrum channel.
