摘要： A RAKE receiver is adapted to receive input from at least a first and a second antenna (104a, 104b). The RAKE receiver comprises a despreading unit (303) adapted to allocate a number (Nf) of despreading fingers to a number of delay positions of a signal which is transmitted over a channel. The RAKE receiver further comprises a delay position selection unit (305) which estimates an antenna correlation (formula 1) between the at least first and second antenna (104a, 104b) and controls the despreading unit (303) according to a first strategy for allocating the number (Nf) of fingers if the antenna correlation (formula 1) is below a predetermined threshold, and according to a second strategy otherwise. The threshold (formula 2) is selected based on at least one of the following: number of available finger in the RAKE receiver (Nf), dispersion of the channel, range of direction of arrivals (Δφ).

摘要： The teachings herein disclose interference cancellation processing that uses hard decision logic for simplified estimation of interfering signals, in combination with soft scaling of the hard decisions for better interference cancellation performance, particularly in low signal quality conditions. In one aspect, the soft scaling may be understood as attenuating the amount of interference cancellation applied by a receiver, in dependence on the dynamically changing received signal quality at the receiver. More attenuation is applied at lower signal quality because the hard decisions are less reliable at lower signal qualities, while less (or no) attenuation is applied at higher signal qualities, reflecting the higher reliability of the hard decisions at higher signal qualities. Signal quality may be quantized into ranges, with a different value of soft scaling factor used for each range, or a soft scaling factor may be calculated for the continuum of measured signal quality.
摘要翻译：本文的教导公开了干扰消除处理，其使用硬判决逻辑来简化干扰信号的估计，结合硬判决的软缩放以获得更好的干扰消除性能，特别是在低信号质量条件下。在一个方面，软缩放可以被理解为根据接收机处的动态变化的接收信号质量来衰减由接收机施加的干扰消除量。在更低的信号质量下应用更多的衰减，因为在较低的信号质量下硬判决不太可靠，而在更高的信号质量下应用更少（或不）衰减），这反映出在较高信号质量下硬判决的可靠性更高。信号质量可以被量化到范围内，具有用于每个范围的软缩放因子的不同值，或者可以为测量信号质量的连续性计算软缩放因子。

摘要： In one or more embodiments, an over-sampling method and corresponding over-sampling circuit efficiently generate an over-sampled signal by determining sampling phases in the over-sampled signal that are unused by downstream processing of the over-sampled signal, and skipping the generation of output values for the over-sampled signal that correspond to the unused sampling phases. In a communication receiver embodiment, determining the unused sampling phases comprises, with respect to currently estimated multipath delays of a received communication signal from which the over-sampled signal is derived, determining which sampling phases in the over-sampled signal will not be used by a downstream processing circuit having known processing delay assignment constraints. The known delay assignment constraints comprise Rake finger placement constraints or channel equalizer tap placement constraints, for example.

摘要： A subset of modeled impairment correlation terms are selected for use in received signal processing. According to one embodiment, a subset of modeled impairment correlation terms is selected and a composite impairment correlation term is determined based on the subset of modeled impairment correlation terms. The composite impairment correlation term may be determined by scaling the modeled impairment correlation terms included in the subset by respective model fitting parameters. The scaled modeled impairment correlation terms are then combined to form the composite impairment correlation term. The subset of modeled impairment correlation terms may be selected based on their respective model fitting parameters. In one embodiment, the modeled impairment terms having a model fitting parameter that satisfy a threshold are included in the subset while those that do not are excluded. The composite impairment correlation term may be used for received signal processing, e.g., demodulation or signal-to-interference estimation.

摘要： Method and system are disclosed for providing advanced RAKE delay control in wireless communications systems. The RAKE delay control method and system of the invention is capable of tracking presently known paths over time and merging the tracking results with new path searcher results. The invention is particularly suitable for devices where the resources (e.g., computational load, power) available for detecting the multipath components are limited. The result is a resource efficient architecture for positioning the RAKE fingers to best extract the signal power available in the channel and to utilize the inherent diversity due to the multipath nature of the signal.

摘要： A target link signal may be received at a receiving device with the target link signal being received in a received signal also including an interfering link signal. A quality of the interfering link signal in the received signal may be estimated at the receiving device to provide an estimated interfering link signal quality. One of a plurality of interference cancellation techniques may be selected responsive to the estimated interfering link signal quality, and an interference cancellation signal may be generated using the selected one of the plurality of interference cancellation techniques. Information of the interference cancellation signal may be incorporated in the received signal. Responsive to incorporating information of the interference cancellation signal in the received signal, the received signal may be demodulated to provide a demodulated target link signal, and the demodulated target link signal may be decoded to provide a target link bit stream.
