ABSTRACT:
The present invention is a fast fading packet diversity transmission method and system for reducing the effects of multipath fading on slow fading channels. One embodiment of the present invention includes a modulator for modulating information packets and a plurality of M multipliers for transmitting the modulated information packets from M antennas with up to M sets of M fixed phase offsets. Another embodiment of the present invention transmits a first group of information packets from M antennas with up to M sets of M fixed phase offsets and a second group of information packets with M slow time varying phase offsets.
