单极性码元的误比特率计算，画出误比特率曲线。(Unipolar symbol of bit error rate calculation, to give the BER curves.)

asr.matlab 有關語音辨識應用於與matlab語言(about the speech recognization for matlab)

在PDSCH信道下，运用非正交的知识做的系统级仿真，并采用编码译码方式降低用户的误码率。(In PDSCH channel, the use of non-orthogonal knowledge to do system-level simulation, and the use of codec way to reduce user error rate.)

说明：  极化SAR(POLSAR)

用matlab实现从原始视频中提取关键帧，并且自动生成新视频，新视频只由关键帧组成从而实现视频总结。(Using matlab realize extracted from the original video key frame, and automatically generate a new video, new video key frame composed by only enabling the video summary.)

第 5 代移动通信系统 (5G) 是面向 2020 年之后的新一代移动通信系统 , 其技术发展尚处于探 索阶段 . 结合国内外移动通信发展的最新趋势 , 本文对 5G 移动通信发展的基本需求、技术特点与可 能发展途径进行了展望 , 并分无线传输和无线网络两个部分 , 重点论述了富有发展前景的 7 项 5G 移 动通信关键技术 , 包括大规模天线阵列、基于滤波器组的多载波技术、全双工复用、超密集网络、自 组织网络、软件定义网络及内容分发网络 . 本文还概括性地介绍了国内 5G 移动通信的相关研发活 动及其近期发展目标 .(The fifth generation mobile communication system (5G) is a new generation of mobile communication system after 2020. Its technological development is still in the exploratory stage. Combining with the latest trends of mobile communication development at home and abroad, this paper prospects the basic needs, technical characteristics and possible development ways of 5G mobile communication development, and divides wireless transmission and wireless network into two parts, focusing on rich. Seven key technologies of 5G mobile communication, including large-scale antenna array, filter bank-based multi-carrier technology, full duplex multiplexing, ultra-dense network, self-organizing network, software definition network and content distribution network, are prospected. The related research and development activities and recent development goals of 5G mobile communication in China are also briefly introduced in this paper.)
