Mimo transmission system in a radio communications network

Abstract

Described is a transmission system () for transmitting an information signal () via a plurality of subchannels from a transmitter () to a receiver (). The transmitter () comprises a demultiplexer () for demultiplexing the information signal () into a plurality of information subsignals (). The transmitter () further comprises a channel encoder () for encoding the information subsignals () into encoded information subsignals (). Each encoded information subsignal () is transmitted via one of the subchannels to the receiver (). The receiver () comprises a channel decoder for successively decoding the received encoded information subsignals. The transmission system () is characterized in that the demultiplexer () is arranged for demultiplexing the information signal () into a plurality of partly overlapping information subsignals () comprising shared and non-shared information elements. For each subsignal () a distribution of the shared information elements is adapted to the throughput of the subchannels as ordered by the receiver (). The channel decoder is arranged for decoding a received encoded information subsignal by incorporating shared information elements of already decoded information subsignals. In this way, the transmission system can achieve a maximum througput.
