Patent ID: 7313168

Claim:
In a radio receiver for use in a radio communication network, an improvement of a receiver for receiving a transmitted radio signal, the signal being subject to distortion, said receiver comprising: a first stage for receiving indications of the radio transmission and processing the indications in order to at least partially mitigate the distortion, and producing an estimation of the transmitted radio signal as an output; a second stage for receiving the output of the first stage and processing the output of the first stage to further refine the estimation; and a third stage for receiving the output of the second stage and processing the output of the second stage to further refine the estimation; and at least one additional stage that is subsequent to the third stage for receiving the output of the stage preceding the at least one additional stage and processing the received output further to refine the estimation, wherein the second stage and the third stage form a parallel interference canceller (PIC), and wherein at least one stage that is subsequent to the first stage comprises a linear minimum mean-square error (LMMSE) receiver.
