System and method of distributed interference cancelation based on delayed channel gain information

A receiver device for a system of distributed interference cancelation based on delayed channel gain information for a plurality of transmitters and respective receivers, wherein the receiver device comprises a processor and executable code which configures the processor to:

• receive an encoded symbol stream signal transmitted by a transmitter device, wherein repetition coding was applied by each transmitter to a symbol stream to obtain an encoded symbol stream;
• receive compressed interference signals of said system transmitters, wherein distributed interference compression was applied by each transmitter to said symbol stream and to the delayed channel gain information, to obtain a compressed interference signal;
• sum the received compressed interference signals of said system transmitters, except the received compressed interference signal from said transmitter device, to obtain an aggregate compressed interference signal;
• apply a distributed interference compression to the received symbol stream signal and to channel gain information to obtain a received compressed signal;
• and
• subtract from the received compressed signal the aggregate compressed interference signal to obtain an interference-free signal,
• wherein said distributed interference compression is calculated such that the interference generated by each transmitter is the same, at the receivers, after distributed interference compression by each receiver.
