Abstract
A method for transmitting data includes mapping a first coded information bit stream intended for a first transmit antenna onto at least one first spreading sequence of a plurality of first spreading sequences to generate a first data stream, mapping a second coded information bit stream intended for a second transmit antenna onto at least one second spreading sequence of a plurality of second spreading sequences to generate a second data stream. The method also includes transmitting the first data stream and the second data stream on respective transmit antennas.
