    摘要: Adaptive reconfiguration of a wireless receiver is enabled based on channel geometry. According to an embodiment, the wireless receiver includes a geometry factor processing module and signal processing modules, e.g. such as but not limited to an SIR estimation module, a power estimation module, a despreading module, a low-pass filter, a combing weight generation module, a coefficient estimation module, a synchronization control channel interference canceller module, etc. The geometry factor processing module determines a geometry factor for the channel over which signals are transmitted to the wireless receiver, the geometry factor being a measure of the ratio of total transmitted power received by the wireless receiver to total interference plus noise power at the wireless receiver. One or more of the receiver signal processing modules are reconfigurable based on the geometry factor.

    摘要: The present invention provides a method and apparatus for adapting a current path delay estimate for path delay tracking. In order to determine the path delay an operating mode is selected and a set of hypothesized path delays are determined based on said operating mode. A metric for each hypothesized path delay is determined, and a current path delay estimate is adapted based on the computed metrics for the hypothesized path delays.

    摘要: Methods and wireless receivers (5) are disclosed for estimating a propagation channel response that includes two closely spaced delays. An exemplary method comprises selecting (720) a plurality of receiver processing delays for sampling the received signal so that that the receiver processing delays span two closely spaced channel response delays, and calculating (730) an average channel coefficient magnitude over at least a first number of time slots of the received signal, for each of the receiver processing delays. The exemplary method further comprises estimating (740) delay timing for each of the two channel response delays, based on the average channel coefficient magnitudes and a multi-delay superposition model for the channel response, and calculating (750) complex channel gains for each of the two channel response delays, based on the estimated delay timings and channel response measurements taken over a second number of time slots that is less than the first number of time slots.
