Abstract
Se proveen técnicas para administrar la interferencia para el handoff suave y para los servicios de transmisión en un sistema de comunicaciones inalámbricas de saltos de frecuencia (es decir, un sistema OFDMA). Estas técnicas pueden ser utilizadas en los enlaces directo e inverso. En un primer esquema, se utiliza una función de FH, fsho (r,T) para los usuarios de handoff suave, se utiliza una función de FH fs1 (k,T) para los usuarios que no utilizan el handoff suave en cada sector si, y la función fsi (k,T) es modificada para que sea ortogonal con respecto a la función de FH, fsho, (r,T), si y cuando es necesario. En un segundo esquema, la función de FH, fsho (r,T), utilizada para los usuarios de handoff suave es por definición ortogonal o tiene una baja correlación con respecto a la función de FH, fsi (k,T) utilizada para usuarios que no se hallan en handoff suave en cada sector si, de forma tal que la modificación de la función de FH, fsi (k,T) no es necesario. La función de FH, fsi (k,T) para cada sector puede ser por definición seudo aleatoria con respecto a las funciones de FH, fsi (k,T) para otros sectores.
