Abstract

Sistemas y metodologías que facilitan la realizacion de la nulificacion de la interferencia y la prediccion de rango en un terminal de acceso. Es posible implementar multiples tipos de demoduladores de receptor en el terminal de acceso, y por ello es posible estimar una matriz de covarianza de la interferencia. Es posible calcular las SNR para los diversos tipos de demoduladores de receptor, y puede identificarse y generarse respectivamente un rango optimo e informacion de CQI asociada, la cual informacion puede seguidamente transmitirse a un punto de acceso. Por lo menos uno de los tipos de demoduladores de receptor puede llevar a cabo un protocolo de nulificacion de la interferencia. Por ejemplo, los tipos de demoduladores de receptor pueden comprender por lo menos un demodulador de nulificacion de la interferencia de error medio cuadrático mínimo (MMSE-IN, minimum mean-squared error interference mulling), junto con uno o más demoduladores de combinacion de relaciones máximas (MRC, maximal ratio combining) y un demodulador de errores cuadráticos medios mínimos (MMSE, minimum mean squared error).
