EP0952684A3

A wireless telecommunications system that mitigates the effect of multipath fading

Abstract

A wireless telecommunications system is disclosed that mitigates multipath fading through an improvement in transmit diversity. Furthermore, embodiments of the present invention are well-suited for use with all forward channel multiplexing schemes (e.g., frequency-division multiplexing, time-division multiplexing, code-division multiplexing, etc.) and all modulation techniques (e.g., amplitude modulation, frequency modulation, phase modulation, etc.). An illustrative embodiment of the present invention comprises: a signal inverter (613) for inverting and alternately not-inverting a first signal in accordance with a schedule (615) to create a second signal; a first antenna for transmitting the first signal; and a second antenna for transmitting the second signal.
