Patent ID: 7167506

Claim:
A RAKE receiver for processing a received electromagnetic signal being a superposition of signal components of different signal propagation paths, the RAKE receiver comprising: an analog-to-digital converter adapted to digitize the received signal; a correlator adapted to decorrelate the digitized signal using a code sequence; first circuitry adapted to generate received symbols from the decorrelated signal; second circuitry adapted to generate, from the received symbols, derotated symbols for a first signal component corresponding to a first signal propagation path; third circuitry adapted to generate, using the received symbols and the derotated symbols, an estimated phasor for the first signal component, wherein the derotated symbols are used to generate symbol decisions for the received electromagnetic signal; and fourth circuitry adapted to generate a corrected phasor for the first signal component from the estimated phasor by reducing multipath interference from one or more other signal components corresponding to one or more other signal propagation paths, wherein the second circuitry is adapted to generate the derotated symbols using the corrected phasor.
