中文摘要： 可用的无线频谱资源日益稀缺，对其高效利用有利于持续发展，同时复杂的无线传输环境对系统自身的抗衰落性能提出了越来越高的要求。为此，本项目将对具有超窄频谱的高效扩展二元相移键控调制（EBPSK）在衰落信道下的性能进行详细探讨。首先，研究EBPSK调制波形和多功能冲击滤波器的优化方法，建立基于EBPSK的通用高效自适应调制解调器物理层的完整技术框架和理论体系；其次，分析不同衰落信道下的EBPSK系统传输性能，提出并搭建衰落信道下的自适应变速率高效通信系统仿真平台，并通过增加信源信道编码等来进一步提升系统性能；最后，建立衰落信道下EBPSK调制的能耗模型，推导出特定信道条件下使系统能耗最小的最佳调制参数，以实现绿色通信。本项目最终研究成果有望建立一套全新的高效EBPSK抗衰落调制解调理论体系，为高效传输系统在实际中得以应用奠定坚实的基础。

英文摘要： Available resources of wireless spectrum have become increasingly scarcity, the efficient utilization of which is beneficial to the sustainable development. Meanwhile, the complexity of wireless transmission environment raises a higher-and-higher demand for the anti-fading performance of the system. Therefore, this project will study the performance of extended binary phase shift keying (EBPSK) with ultra-narrow spectra in the fading channel. Firstly, this project will optimize the modulation waveform of EBPSK and impacting filter,and then build a complete technical framework and theory system for the general, efficient and adaptive modem based on EBPSK in physical layer. Secondly, aiming at the different fading channel model, this project is to analyze the transmission performance of the EBPSK system and establish a simulation platform for the adaptive variable-rate and efficient communication system in the fading channel, furthermore we will improve the system performance by adopting source and channel coding. Finally,the energy consumption of EBPSK modulation in fading channel is modeling, which gives the optimum modulation parameters to minimize the energy consumption in given channel, so green communication can be realized. The final research results are hoped to establish a novel efficient anti-fading modu
