MassiveMIMO信号检测算法的性能分析

大学本科生毕业设计(论文)摘 要目前 5G 无线通信是一个正热话题，其关键技术之一 Massive MIMO 技术是一个正热的研究领域。在 Massive MIMO 各项技术中，信号检测是一个尤为重要的技术。为了提高系统检测性能、降低计算复杂度且获得很好的各项增益，信号检测算法研究的重要性不言而喻。该文研究了 Massive MIMO 一部分传统的信号检测算法。这其中包括了最为常用的迫零检测算法、最小均方误差检测算法、基于前两者算法的串行干扰检测算法和最大似然检测算法。在 BPSK 和 16-QAM 两种不同的调制方式下，该文运用 MATLAB 进行系统和算法的仿真，通过计算误码率绘制成图分别比较了几个算法的检测性能。仿真结果对比得出，最大似然检测算法性能最优，MMSE-SIC 其次，ZF-SIC优于最小均方误差检测算法，迫零检测算法由于会放大噪声性能最不理想。不过 ML 算法的计算复杂度也最高，检测所需时间长。串行干扰检测算法计算复杂度比线性检测算法要高。通过对比传统信号检测算法可以得知算法中的不足，对后续研究打下基础。- I -关键词： Massive MIMO，信号检测算法，算法性能分析大学本科生毕业设计(论文) Performance Analysis of Massive MIMO signal detection algorithmAbstractNowadays, 5G wireless communication is popular.
