Abstract

We 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 antennas. We show that this new scheme greatly improves the throughput over currently known multiple antenna methods. We also find the optimal power allocation strategy among multiple transmit antennas for a fixed feedback rate.
