Mimo transmission system in a radio communications network

A transmitter (12) for transmitting an information signal (21) via a plurality of subchannels to a receiver (16), the transmitter (12) comprising a demultiplexer (20) for demultiplexing the information signal (21) into a plurality of information subsignals (23), the transmitter (12) further comprising a channel encoder (8) for encoding the information subsignals (23) into encoded information subsignals (25), wherein each encoded information subsignal (25) is transmitted via one of the subchannels to the receiver (16), characterized in that the demultiplexer (20) is arranged for demultiplexing the information signal (21) into a plurality of partly overlapping information subsignals (23) comprising shared and non-shared information elements, wherein for each subsignal (23) a distribution of the shared information elements is adapted to the throughput of the subchannels as ordered by the receiver (16).

A receiver (16) for receiving encoded information subsignals via a plurality of subchannels from a transmitter (12), the receiver (16) comprising a channel decoder for successively decoding the received encoded information subsignals, characterized in that the encoded information subsignals are partly overlapping encoded information subsignals comprising shared and non-shared information elements, wherein for each subsignal (23) a distribution of the shared information elements is adapted to the throughput of the subchannels as ordered by the receiver (16), the channel decoder being arranged for decoding a received encoded information subsignal by incorporating shared information elements of already decoded information subsignals.

A method of transmitting an information signal (21) via a plurality of subchannels to a receiver (16), the method comprising:

• demultiplexing the information signal (21) into a plurality of information subsignals (23),
• encoding the information subsignals (23) into encoded information subsignals (25),
• transmitting each encoded information subsignal (25) via one of the subchannels to the receiver (16), characterized in that the information signal (21) is demultiplexed into a plurality of partly overlapping information subsignals (23) comprising shared and non-shared information elements, wherein for each subsignal (23) a distribution of the shared information elements is adapted to the throughput of the subchannels as ordered by the receiver (16).
