Abstract:This paper analyzes the effect of channel gains on the performance of signal detection in Multiple Input Multiple Output(MIMO) systems,and based on that this paper proposes an intelligent MIMO signal detection algorithm.It dynamically chooses child-node number according to the gains between antennas.While keeping the detection performance close to Maximum Likelihood(ML) algorithm,it can reduce up to 54% extension nodes compared with traditional K-best algorithm.Based on the proposed algorithm,a dynamic reconfigurable Very Large Scale Integrated Circuit(VLSI) MIMO detector is designed and implemented,and it can support 4×4 antennas,demodulates QPSK and 16-QAM signals with throughput up to 800 Mb/s.
Keywords:channel analysis  dynamic reconfigurable  K-best algorithm  Multiple Input Multiple Output(MIMO) detector  Very Large Scale Integrated Circuit(VLSI) design
