Abstract
Un receptor reduce la interferencia en un simbolo recibido de interes que se puede atribuir a un simbolo de interferencia que utiliza conocimiento de los codigos de propagacion de simbolos. El receptor comprende una pluralidad de correlacionadores que generan valores despropagados para el simbolo recibido de interes y el simbolo de interferencia, y un combinador para combinar los valores despropagados utilizando las ponderaciones de combinacion calculadas basandose en correlaciones de codigo de propagacion entre los codigos de propagacion para el simbolo recibido de interes y el simbolo de interferencia.A receiver reduces interference in a symbol received of interest that can be attributed to an interference symbol that uses knowledge of the symbol propagation codes. The receiver comprises a plurality of correlators that generate depropagated values for the received symbol of interest and the interference symbol, and a combiner to combine the depropagated values using the combination weights calculated based on propagation code correlations between the propagation codes for the symbol received of interest and the symbol of interference.
