摘要： 为减少高速通信系统中硬件资源的消耗，设计一种应用于MIMO-OFDM无线通信系统中的高速信号检测器，根据可重构设计的需求，提出一种简化K-BEST(SKB) MIMO信号检测算法，介绍可配置型硬件结构，并采用Xilinx Vertex-4 FPGA平台加以实现。仿真实验结果表明，该检测器的最高数据吞吐率可达2 Gb/s，并能针对不同星座调制信号(如QPSK, 16-QAM)进行检测。

Abstract: In order to reduce the hardware consumption in high speed communication system, a high speed Multi-Input and Multi-Output(MIMO) signal detector applied for MIMO-OFDM wireless communication system is presented. According to the the requirement of reconfigurable design, a Simplified K-Best(SKB) algorithm as well as a reconfigurable structure for MIMO signal detector is proposed. The MIMO signal detector is implemented on Xilinx Vertex-4 FPGA platform. Simulation experimental results show the throughput of this detector achieves 2 Gb/s and has the function of demodulating different modulation such as QPSK and 16-QAM.
