Abstract: The invention provides a spread spectrum communication system for maintaining an initial transmit power level of a communication station during periods of inactivity. The system comprises a first station (501) and a second station (502), the initial transmit power level of which is maintained, wherein the first station generates an automatic power control signal by comparing a measured noise power level in a communication channel and an estimated system transmit power level and the second station occasionally transmits a spread spectrum signal whilst in an inactive state and receives the automatic power control signal to adjust an initial transmit power level thereof.

Abstract: Un método para conservar la capacidad de un enlace inalámbrico RSDI de sistema de comunicación de espectro ensanchado incluyendo un primer transceptor de espectro ensanchado y un segundo transceptor de espectro ensanchado, recibiendo dicho primer transceptor de espectro ensanchado una señal de datos digitales que incluye un patrón de bandera predeterminado correspondiente a un periodo de reposo y que transfiere la señal de datos digitales a dicho segundo transceptor como señal de espectro ensanchado, y recibiendo dicho segundo transceptor de espectro ensanchado la señal de espectro ensanchada y emitiendo la señal de datos, consistiendo el método en los pasos de: demora, por el primer transceptor, de la señal de datos digitales para formar una señal de datos digitales diferida; monitorización de la señal de datos digitales para detectar el patrón de bandera predeterminado; transmisión de la señal de datos digitales como la señal de espectro ensanchado al segundo transceptor; suspensión de latransmisión de la señal de datos digitales cuando está presente el patrón de bandera; detección, por el segundo transceptor, de la ausencia de señal de datos digitales diferida; e inserción del patrón de bandera predeterminado en la señal de datos digitales emitida.

Abstract: A first detector receives a received signal and extracts the data signals from the received signal. A hard decision converter converts soft symbols outputted by the first detector into hard symbols. An interference canceller extracts the voice signals from the received signal. A second detector is connected to the output of the interference canceller, and extracts the individual voice signals. The second detector is a different detector type than the first detector.
