Abstract

Abstract:

A novel and effective receiver scheme is presented with Turbo-code in order to effectively overcome the space interference induced by multi-antenna MIMO system. By modifying the conventional Turbo iterative decoding algorithm, new scheme synchronizes the interference detector with Turbo decoder, which can fully utilize original received information from the point of view of information theory. Multi-receive antennas can also provide the diversity gain for LLR information and iterative extrinsic information. The scheme breaks the restriction of space and time domain of STBC and BLAST. Simulation results verify the validity of the scheme from system performance and iterative parameters.

Key words: Turbo-MIMO, iterative decoding, extrinsic information, diversity gain
