Patent ID: 7508863

Claim:
A method of processing signals, comprising: receiving multi-path signals using a rake receiver; determining channel estimates using a channel estimation unit for the received multi-path signals; applying combining operation using a combination unit to the multi-path signals to obtain a received signal, the combining operation being a function of a correlation matrix of the received multi-path signals, a correlation matrix of estimates for channels of the received multi-path signals, and a cross-correlation matrix of the channels and channel estimates for the received multi-path signals; and wherein the correlation matrix of the received multi-path signals is a function of a correlation matrix of the received multi-path signal channels and a correlation matrix of noise on the received multi-path signal channels; the correlation matrix of estimates for channels of the received multi-path signals is a function of the correlation matrix of the received multi-path signal channels and a cross-correlation matrix between effective noise and channel estimation error; and the cross-correlation matrix of the channels and channel estimates for the received multi-path signals is a function of the correlation matrix of the received multi-path signal channels and a correlation matrix of error in the estimates for channels of the received multi-path signals.
