CDMA transceiver techniques for multiple input multiple output (mimo) wireless communications

摘要

The present invention is related to a method for multi-user wireless transmission of data signals in a communication system having at least one base station and at least one terminal. It comprises, for a plurality of users, the following steps : adding robustness to frequency-selective fading to the data to be transmitted. performing spreading and scrambling of at least a portion of a block of data, obtainable by grouping data symbols by demultiplexing using a serial-to-parallel operation, combining (summing) spread and scrambled portions of the blocks of at least two users, adding transmit redundancy to the combined spread and scrambled portions, and transmitting the combined spread and scrambled portions with transmit redundancy. <IMAGE>
