Patent ID: 7020446

Claim:
A method for transmitting an input stream of data symbols in a multiple-input/multiple-output wireless communications system, comprising: demultiplexing the input stream into M substreams; adaptively modulating and coding each of the M substreams to a coded substream; space-time transmit diversity encoding a first of the M coded substreams into two space-time transmit diversity encoded output substreams, one space-time transmit diversity encoded output substream to be transmitted by a corresponding one of two transmit antenna; demultiplexing each output substream into a plurality demultiplexed output streams; multiplying each of the plurality of demultiplexed output streams by an orthogonal variable spreading factor; adding the demultiplexed output bitstreams, for each output stream, after multiplication into a summed output stream corresponding to each output stream; multiplying each summed output stream by a scrambling code; and transmitting directly each other coded substream by a corresponding single transmit antenna.
