FPGA Design and Implementation of Channel Equalization Zero Forcing Detection Algorithm

信道均衡技术是为了提高衰落信道中的通信系统的传输性能而采取的一种抗衰落措施。在大规模MIMO系统中,随着天线数目的增加,采用简单的线性预编码如ZF(迫零)算法就可以近似逼近DPC实现最优性能。本文主要基于5G新空口研究FPGA上实现ZF检测算法求解信道均衡问题,并进行验证。验证结果表明该算法能很好地实现信道均衡功能。

Channel equalization is an anti-fading measure to improve the transmission performance of communication system in fading channel. In large-scale MIMO systems, with the increase in the number of antennas, simple linear precoding such as ZF(Zero Forcing) algorithm can approximate DPC to achieve optimal performance. Based on 5 G New Ratio, this paper mainly studies the channel equalization problem by implementing ZF detection algorithm on FPGA. This function can be verified. Verification results show that the algorithm can achieve channel equalization function well.
