用于Massive MIMO系统的LAS检测器误比特率性能仿真摘 要 　　二十世纪至今通信业发展趋势讯速，在这个进程中经历了两回最重要的变革转型，一是从有线通信网络到无线通信系统网络的演变，二是从模拟通信到数据通信的演变。这当中移动通信网的技术持续保持迅速进展的走势，在数十载间推陈出新和不断改善。　　在面对智能物联、虚拟技术、人工智能应用等新科技的迅速发展，当前的无线信号时有发生频谱资源供不应求、频谱使用效率低下、能耗的效率差明显等状况。为了能够更妥善地解决以上的状况，第五代移动通信系统大势所趋。5G享有功能卓越、低拥塞与高容量的属性，而以上的优势主要集中体现在毫米波通信、小无线基站、全双工、新式多址还有Massive MIMO这5大技术应用上。 　　鉴于伴随着发送与接收的无线天线数的增长，信号检测的算法复杂度也继而增长。对于Massive MIMO系统来说，那些我们熟知的传统检测算法，对应的复杂度是非常高的。基于这个现象，如何使上行链路检测算法的性能提高成为了本文的主要研究对象，经过对LAS计算方式的机制展开解读、对误比特率性能指标展开研究，经过MATLAB分別对各种数目的发射端和接收端下展开误比特率性能指标的仿真模拟，谈论ZF-LAS与MMSE-LAS在各种通信前提下的性能指标，进而对LAS计算方式有着深入的理解。谈论LAS在Massive MIMO中的应用，进而完成对这一计算方式的研究。 关键词 多入多出 大规模多入多出 信号检测 似然上升有哪些信誉好的足球投注网站 邻域有哪些信誉好的足球投注网站 　　BER simulation for LAS detectors with Massive MIMO Wireless Systems ABSTRACT 　　The development trend of the communication industry in the 20th century to now is fast. In this process, it has experienced two most important transformations: one is the evolution from wired communication network to wireless communication system network, and the other is the evolution from analog communication to data communication. In this process, the technology of mobile communication network continues to advance rapidly, innovating and improving continuously over the decades. 　　Faced with the new technologies such as the IOT and so on, the current wireless signal often suffers from such problems as short supply of spectrum resources, low efficiency of spectrum uses and obvious poor efficiency of energy consumption. In order to be able to solve the above situation more properly, the fifth mobile communication system is the general trend. 5G is characterized by excellent functionality, low congestion and high capacity, and these advantages are mainly reflected in millimeter-wave communication, small wireless base station, full duplex, new multiple access and Massive MIMO. 　　As the number of wireless antennas transmitted and received increases, the algorithm complexity of signal detection also increases. For Massive MIMO system, the complexity of the trad
