Abstract

A transmission system has a transmitter and a receiver for transmitting data along a transmission channel that has non-uniform quality in time and/or in space as relating to the receiver. The transmitter first distributes the data into successive uniform sized data blocks, and within each block the data into uniform sized groups. Furthermore it encodes within each group the data by an error protective code that is separate from any other group. The transmitter furthermore distributes the encoded data of each group into uniform-sized data packets and assigns the packets from respective groups uniformly and cyclically within a block to a series of time- and/or space-interleaved and multiplexed sub-channels. The system furthermore for each group within a particular block controls a respective different transmission power level.
