摘要：
In this paper, an enhanced single-binary (SB) turbo decoding scheme is proposed to provide reliable extrinsic information to the detector of turbo multiple-input multipleoutput (MIMO) system. By using the state metrics of the systematic bits of SB turbo decoding, the proposed scheme generates the extrinsic information of parity bits with reduced operations. Simulations of a 4 x 4 turbo MIMO system under 16-QAM modulation and Long Term Evolution (LTE) rate-1/3 turbo code reveals that this proposed scheme combined with multiplying extrinsic information by distinct scaling factors achieves BER performance gains compared with the conventional scheme.
