Abstract
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 where for a plurality of users have robustness to frequency-selective fading added to the data to be transmitted, then grouping data symbols into blocks formed by demultiplexing a serial-to-parallel operation, and spreading and scrambling a portion of the obtained blocks of data, followed by combining spread and scrambled portions of the blocks, adding transmit redundancy to the combined spread and scrambled portions which is then transmitted.
