    Abstract: A reconfigurable multi-code correlation unit for correlating a sequence of chip samples comprising 1) a memory for storing the chip samples; 2) a plurality of add-subtract cells, each add-subtract cell receiving a plurality of real bits, a, and a plurality of imaginary bits, b, from a first chip sample and storing each real bit, a, and each imaginary bit, b, in a data store; and 3) a plurality of sign select units. Each sign select units receives from one add-subtract cell a plurality of first inputs equal to a sum (a+b) of the real bits, a, and the imaginary bits, b, and a plurality of second inputs equal to a difference (a−b) of the real bits, a, and the imaginary bits, b. Each sign select unit generates a plurality of real outputs and a plurality of imaginary outputs, wherein each of the real and imaginary outputs is equal to one of 1) the sum (a+b) multiplied by one of +1 and −1 and 2) the difference (a−b) multiplied by one of +1 and −1.

    Abstract: A method of processing digital samples of a signal received at a receiver of a wireless communication system includes monitoring channel conditions and generating a channel indicator including at least one channel parameter by performing at least one of: estimating a channel mobility parameter and comparing it with a threshold; estimating a channel parameter of the energy of the channel outside a predefined temporal window and comparing it with a threshold; estimating a channel temporal duration parameter and establishing if it meets predetermined criteria; estimating a channel-zero location parameter and establishing if it meets predetermined criteria; estimating a received-signal signal-to-disturbance power ratio and comparing it to a threshold; estimating an estimated-channel-response signal-to-disturbance power ratio; estimating the degree of non-stationarity of the disturbance at the receiver input; and selecting one of a plurality of processing routines for processing the digital samples based on said channel indicator. Related receivers are also described.

    Abstract: A multi-carrier RAKE receiver is described herein. The multi-carrier RAKE receiver distributes RAKE fingers between a plurality of received carriers based on a comparison between the signal-to-interference ratios (SIRs) determined for each carrier. In one embodiment, the RAKE fingers are distributed evenly between the carriers when a comparison between the largest and smallest SIR is less than or equal to a threshold. In another embodiment, the RAKE fingers are distributed to favor the carrier(s) with the strongest SIR(s) when the comparison between the largest and smallest SIR exceeds the threshold. By distributing the RAKE fingers to favor the carriers with the strongest SIRs, the embodiments of the present invention enable the system designers to limit the total number of available RAKE fingers without sacrificing performance.

    Abstract translation: 本文描述了多载波RAKE接收机。 基于为每个载波确定的信号干扰比（SIR）之间的比较，多载波RAKE接收机在多个接收载波之间分配RAKE指。 在一个实施例中，当最大SIR和最小SIR之间的比较小于或等于阈值时，RAKE指状物均匀分布在载波之间。 在另一个实施例中，当最大和最小SIR之间的比较超过阈值时，RAKE指状分配以支持具有最强SIR的载波。 通过分配RAKE手指以使SIR具有最强的载波，本发明的实施例使得系统设计者能够在不牺牲性能的情况下限制可用的RAKE手指的总数。
