New Spread Spectrum Techniques for Multiple Antenna Transmit Diversity

Conference PaperWe propose a new scheme for multiple antenna transmission in the context of spread spectrum signaling. The new scheme consists of using shifted Gold sequences to modulate independent information on the multiple atennas. We show that this new scheme greatly improves the throughout over crrently known multiple-antenna methods. We also find the optimal power allocation strategy among multiple transmit antennas for a fixed feedback rate.Noki
