中文摘要： 作为无线高速个域网中一项强有力的候选技术，60GHz毫米波通信技术成为当前学术界的研究热点。60GHz系统中的射频器件非线性将在实际设计中在所难免，而毫米波系统中载波频率偏移现象也非常严重，同时毫米波信号衍射能力十分有限，毫米波系统所具备的上述特殊已然使传统的信号处理框架难以适用。本课题旨在探索研究适合于60GHz毫米波系统的先进信号处理框架。针对存在射频非线性下的信号检测问题，拟分别基于粒子滤波与马尔科夫链蒙特卡洛算法，设计一类低复杂度、高性能的联合参数估计与数据检测方案；为了有效降低载频偏移所带来的负面影响，基于粒子滤波进一步提出一种高性能的频偏与数据联合估计方案；最后，从虚拟反光镜理论与物理层编码两个全新角度出发，研究链路遮挡情况下的信号连续性传输方案。本课题研究有望在新型高性能信号处理与传输机制方面取得突破性进展，对60GHz毫米波无线通信系统设计具重要理论意义与良好应用价值。

英文摘要： As a promising candidate for high-speed wireless personal area networks (WPAN), 60GHz millimeter-wave communication has emerged as a popular technique drawing the worldwide interests. Unfortunately, the most current researches on 60GHz millimeter-wave communications mainly focus on the development of radio-frequency devices, while the signal processing of great importance to practical communications and transmissions procedure has not yet been thoroughly investigated. The remarkable nonlinearity of radio-frequency (RF) devices is usually inevitable for millimeter-wave systems. Also, the diffracting ablity of millimeter-wave signal is significantly limited. Taking these unique properties of 60GHz millimeter-wave systems into considerations, this project will carry out an in-depth study on the signal processing and transmissions in 60GHz millimeter-wave communications. Our investigations will concentrate on the following aspects: (1) Joint power-amplifier nonlinearity estimation and data detection; (2) joint carrier frequency shift estimation and data detection; and (3) the algorithms to ensure the transmission continuity and link stability in the presence of obstruction-introduced non-line-of-sight links. From the two perspectives (perspectives) of both physical design and MAC schedule, this research aims to prov
