自己写的一个OFDM发送接收的程序，注释详尽，适合初学者，有图形验证。可实现IFFT过采样，以及prefix-Writing their own to send an OFDM reception process, detailed notes, suitable for beginners, there is graphical verification. Can achieve over-sampling IFFT and prefix

这个模拟器可以被用来衡量和情节网络容量性能和信号干扰比 （SIR） 性能的 LTE 网络与整数频率复用方案与重用因子 1 （IFR-1）。与重用因子 1 的频率复用方法意味着可用的频率资源使用的 LTE 网络中的所有单元格。级 LTE 由两个 Matlab 脚本文件 （LTE_main.m，LTE_configuration.m）、 三个 Matlab 函数文件 （LTE_IFR_sim_dist.m，LTE_IFR_sim_netwide.m，LTE_IFR_plot.m） 和一个 Matlab 垫文件 (bs_user_position.mat) 组成的系统。

Cypress Semiconductor makes a variety of PLL-based clock generators. This application note provides a set of recommendations to optimize usage of Cypress clock devices in a system. The application note begins with recommended termination techniques for clock generators. Subsequently, power supply filtering and bypassing is discussed. Finally, the application note provides some recommendations on board layout.

移动通信基本知识:从通信网的角度看，移动网可以看成是有线通信网的延伸，它由无线和有线两部分组成。无线部分提供用户终端的接入，利用有限的频率资源在空中可靠地传送话音和数据；有线部分完成网络功能，包括交换、用户管理、漫游、鉴权等，构成公众陆地移动通信网PLMN。从陆地移动通信的具体实现形式来分主要有模拟移动通信和数字移动通信这两部种。-Basic knowledge of mobile communications: From the perspective of communication networks, mobile networks can be seen as an extension of wired communication network, which is both wireless and wired components. Part of user terminals to provide wireless access, frequency of use of limited resources in the air and reliable transmission of voice and data wired part of the completion of network functions, including switching, subscriber management, roaming, authentication and so on, constitute a public land mobile communication network PLMN. From land-based mobile communications to the specific forms of the main points have analog and digital mobile communications that two kinds of mobile communication.
