资料介绍

在多输入多输出(MIMO)系统中分析信道增益对信号检测性能的影响,提出一种基于信道分析的智能MIMO信号检测算法,根据各对天线间的信道增益动态调整子节点扩展数,在检测性能接近最大似然算法性能的前提下,该算法比传统K-best算法减少54%的子节点扩展数。基于该算法设计并实现的动态可重构的超大规模集成电路MIMO检测器支持4×4天线阵列、QPSK/16-QAM调制信号,数据吞吐率达到800 Mb/s。

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.
