Abstract
Se describen los métodos y sistemas para calibrar transceptores. Los componentes del transceptor analogico crean errores, tales como errores de ganancia y de descentrado en una porcion del receptor o una porcion del transmisor, que se compensan ajustando el procesamiento de señal digital en la porcion de cálculo del transceptor. Los errores pueden medirse en un procedimiento de calibracion y los valores de compensacion determinados pueden almacenarse en un dispositivo de memoria del transceptor. Estos valores luego pueden recuperarse cuando el transceptor se inicia para uso durante el procesamiento de la señal de las señales recibidas mediante y transmitidas por el transceptor.
