Abstract:

Abstract: This paper proposes an iterative detection decoding algorithm based on ordered successive interference cancelation (OSIC) for time division long term evolution (TD-LTE) multi-input multi-output (MIMO)
systems. In the algorithm a multiple-codewords transmission mode is used, and the effects of adaptive modulation and coding (AMC) and hybrid automatic repeat request (HARQ) on the detection order are taken into
consideration. Computation complexity of the algorithm is analyzed. Numerical results show that the proposed
method can significantly improve throughput. The performance gain increases with the increase of gaps
between modulation and coding levels of multiple codewords, and the increase of the number of transceiver
antennas.
