【摘要】：为了满足60GHz高速无线通信系统在手持设备上应用的需求,低功耗低复杂度的均衡技术研究日趋活跃。本文以60GHz无线通信系统为主要研究背景和探索课题,主要针对满足60GHz系统的低功耗低复杂度均衡技术,重点研究了时域均衡。本文主要研究内容分为五个部分。第一章介绍了60GHz通信系统的发展现状,对学术界和工业界的最新成果进行了调研。然后对均衡算法国内外的研究历史与现状进行了简单的说明,在系统层面对均衡算法和架构进行针对性的优化与配置是降低60GHz系统复杂度和功耗的重要方法。接着对本文的主要贡献与创新进行了说明。本章最后说明了本论文的结构安排。第二章介绍60GHz通信系统的基本信息,包括频谱分配,信道的传播特性,信道测量方式,60 GHz系统的主要标准以及本项目所使用的物理层帧结构。第三章研究符号间隔均衡器,包括频域迫零(ZF)均衡和最小均方误差(MMSE)均衡,时域MMSE均衡,时域判决反馈均衡(TD?DFE),时域部分判决反馈均衡(TD?PFE)和时域完全判决反馈均衡(TD?CFE),本章详细比较了各种算法的复杂度以及各自的优势。第四章研究分数间隔均衡器。分数间隔均衡器中一个符号不仅只有一个采样点,这将极大降低同步端的复杂度,本章从原理到仿真上对分数间隔均衡器做了研究与分析。最后是全文总结和对未来工作的展望。
[Abstract]:In order to meet the demand of 60GHz high speed wireless communication system in handheld devices, the research of low power and low complexity equalization technology is becoming more and more active.In this paper, the 60GHz wireless communication system is the main research background and research topic, focusing on the low power and low complexity equalization technology for 60GHz systems, focusing on the time domain equalization.The main content of this paper is divided into five parts.The first chapter introduces the development of 60GHz communication system, and investigates the latest achievements of academia and industry.Then the research history and present situation of equalization algorithm at home and abroad are briefly explained. It is an important method to reduce the complexity and power consumption of 60GHz system to optimize and configure the equalization algorithm and architecture at the system level.Then the main contribution and innovation of this paper are explained.At the end of this chapter, the structure of this paper is explained.The second chapter introduces the basic information of the 60GHz communication system, including spectrum allocation, channel propagation characteristics, the main standards of the channel measurement method / 60 GHz system and the physical layer frame structure used in this project.In chapter 3, symbol interval equalizer is studied, including frequency domain zero forcing MMSE equalization, minimum mean square error equalization and time domain MMSE equalization.Time domain decision feedback equalization (TDU DFE), time domain partial decision feedback equalization (TDU PFE) and time domain complete decision feedback equalization (TDU CFE) are compared in detail. In this chapter, the complexity of various algorithms and their respective advantages are compared in detail.In chapter 4, fractional interval equalizer is studied.There is not only one sampling point for a symbol in the fractional interval equalizer, which will greatly reduce the complexity of the synchronization end. In this chapter, the principle and simulation of the fractional interval equalizer are studied and analyzed.The last part is the summary of the full text and the prospect of the future work.
