Abstract

A digital radio telephone apparatus adaptively employs an equalizer for compensating for signal distortion of received signals. A switch may be provided at an output terminal of the equalizer so that the equalized signals are selectively applied to the decoder. The equalizer may be rendered to be operative when the quality of received radio frequency signals is lower than a prescribed level and rendered to be inoperative when the quality of received radio frequency signals is not lower than the prescribed level. The equalizer may be rendered to be inoperative for a predetermined time period from the time a digital speech radio link establishment operation is initiated. In the event that a radio link is established by TDMA (Time Division Multiple Access), the equalizer may be rendered to be operative in synchronization with a time slot assigned to the apparatus. The equalizer is not suppled with electric power or clock while the equalizer is rendered to be inoperative.
