Abstract: A signal-path-selection method in a RAKE receiver includes producing C channel estimates from M received signal paths, determining a plurality of best signal paths using the C produced channel estimates, choosing A signal paths of the plurality of best signal paths in accordance with at least one pre-determined criterion, and combining the A signal paths. C is a measure of channel-estimation capacity of the RAKE receiver. M is greater than C.
Abstract translation: RAKE接收机中的信号路径选择方法包括从M个接收信号路径产生C信道估计，使用C个产生的信道估计来确定多个最佳信号路径，根据该信道估计选择多个最佳信号路径的A个信号路径 至少一个预定标准，并组合A信号路径。 C是RAKE接收机的信道估计容量的度量。 M大于C.

Abstract: A method for use in receiving a spread-spectrum signal includes receiving an input signal. The input signal includes a first plurality of multipath components. The method also includes despreading the first plurality of multipath components. The step of despreading includes computing a plurality of corresponding delays. The method also includes computing a plurality of combining weights based, at least in part, on interference correlation between at least two of the first plurality of multipath components, selecting, according to at least one criterion, a subset of the plurality of combining weights, and despreading and combining a second plurality of multipath components using at least one quantity related to the selected plurality of combining weights and a plurality of delays and multipath components corresponding to the plurality of selected combining weights.
