Transmission method with frequency, time spreading at transmitter involves de-spreading at receiver, adaptation of spreading to e.g. required transmission quality

摘要

The method involves subjecting the information symbols to frequency spreading and time spreading at the transmitter end and subjecting them to a corresp. de-spreading at the receiver end. The spreading and hence system yield are adapted to the required transmission quality and the channel properties Independent claims are also included for an arrangement for implementing the method and for a multiple access signal processing method.
