Abstract:
1. A decorrelating rake receiver comprising: a plurality of filters arranged to be coupled to an input signal and to accept filter coefficients, the plurality of filters operable to provide a plurality of output signals; a coefficient generator, arranged to be coupled to the input signal and the plurality of filters, to explicitly and definitely determine the filter coefficients for the plurality of filters such that the plurality of filters perform a decorrelating rake process; a combiner, coupled to the plurality of filters, to combine the plurality of output signals and provide a received signal; and an autocorrelation processor coupled to the input signal to provide autocorrelation parameters to the coefficient generator, the autocorrelation parameters corresponding to the input signal; wherein the coefficient generator is further coupled to receiver identification information, wherein the coefficient generator further comprises an inversion processor to provide a matrix inverse corresponding to the autocorrelation parameters, and wherein the inversion processor uses a recursive architecture to provide the matrix inverse.
