Abstract

Para recibir paquetes con cancelacion de la interferencia, se reciben transmisiones de bloque para los paquetes sobre bloques de tiempo-frecuencia utilizado por estos paquetes. Se lleva a cabo el procesamiento especial de receptor sobre símbolos ingresados a efectos de obtener símbolos detectados. Cada paquete es demodulado y decodificado sobre la base de la totalidad de los símbolos detectados obtenidos para la totalidad de las transmisiones de bloque recibidas para el paquete. Para cada paquete que se decodifica correctamente, se termina la transmision para el paquete, se estima la interferencia debida al paquete, y la interferencia estimada se reta de los símbolos ingresados para la totalidad de los bloques de tiempo-frecuencia utilizados por el paquete. El procesamiento espacial del receptor se lleva a cabo sobre los símbolos de interferencia cancelada a efectos de obtener nuevos símbolos detectados para la totalidad de los bloques de tiempo-frecuencia utilizados por todos los paquetes correctamente decodificados. Cada paquete decodificado en error y que se superponga, por lo menos parcialmente, con cualquier paquete correctamente decodificado, se puede demodular y decodificar sobre la base de la totalidad de los símbolos detectados disponibles para dicho paquete.
