A METHOD FOR SELECTING A SIGNAL, AND A CELLULAR RADIO SYSTEM

摘要

A method for selecting a signal used in a cellular radio system having base stations and a vocoder encoding a signal. The vocoder is operationally connected to the base stations via transmission paths of different lengths. The base stations receive a signal encoded by the vocoder in the forward direction and transmit a signal to the vocoder in the reverse direction. The cellular radio system includes selectors that are separate from the base stations and that are arranged to select at least one signal to be transmitted to the vocoder from the signals received by the base stations in the reverse direction. The selectors are arranged to distribute to the base stations the signal arriving from the vocoder in the forward direction.
