Title:
RECEIVING DEVICE, PROGRAM, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2013/018466
Kind Code:
A1
Abstract:
An objective of the present invention is to improve detection precision in MIMO detection and multi-user detection using turbo theory. A receiving device which receives a plurality of spatially multiplexed signals from a transmitting device comprises: decoding units (40-1, 40-2) which carry out error correction decoding on the received signals and outputs a coding bit post-LLR and a coding bit external LLR; replica generation units (41-1, 42-2) which generate transmission signal replicas based on the post-LLR and the external LLR; a replica selection unit (50) which selects a combination of transmission signal replicas from the transmission replicas according to the detection subject; a cancelation unit (35) which removes a received signal replica which is created based on the transmission signal replica combination which is selected from the received signals; and a MIMO separation unit (36) which carries out MIMO separation on the signal which has had the received signal replica removed.
