Abstract

Se puede controlar la interferencia al vaciar o atenuar selectivamente potencia de transmision. Un método para estimar interferencia ocasionado por una entidad transmisora en un sistema de comunicacion inalámbrico, comprende determinar un nivel de exactitud deseado en una estimacion de interferencia, determinar el numero requerido de vacíos por conjunto de sub-bandas para lograr el nivel de exactitud deseado, insertar el numero requerido de vacíos por conjunto de sub-bandas en una secuencia de salto de frecuencia (FH), y transmitir de acuerdo con la secuencia FH.
