基于DGTD方法的高效天线建模与仿真研究

说明：  实现20m双绞线有线通讯，一端控制另一端小灯亮暗，反过来，一端发送字符，另一端显示浮点数(Realize 20m twisted-pair cable communication, one end controls the light of the other end, conversely, one end sends characters, the other end shows floating-point numbers.)

说明：  ldpc编码的matlab实现，供大家参考(Matlab implementation of LDPC coding for your reference)

基于OFDM的多准则下认知无线电资源分配问题的研究,认知无线电资源分配(Cognitive radio resource allocation problem of OFDM multi-criteria research, cognitive radio resource allocation)

主要关于ofdma中资源分配动态分配的算法中的注水算法的介绍(it is about waterfilling allocation dynamic allocation of ofdma algorithm introduced)

C++开发104协议，支持主从站。支持多客户端连接(C++ develops 104 protocol to support master and slave stations. Support multi-client connection)

bcjr算法 map形式 适用于卷积码和turbo码(bcjr algorithm map form for convolutional codes and turbo codes)

Offset between filter input samples (see notes).

说明：  stm32实现ook调制，调制通过，误码率较高(The realization of ook modulation by stm32)

本章介绍了用于WAN(广域网)环境的各种协议和技术。在这里概述的题目包括点对点链路，电路交换，分组包交换，虚电路，拨号服务，和WAN设备。在手册第3部分,‘WAN协议’,的各章里将更详细地讲述专门技术。 ( This article introduces the various protocols and technologies used in wide-area network (WAN) environments. Topics summarized here include point-to-point links, circuit switching, packet switching, virtual circuits, dialup services, and WAN devices. Chapters in Part 3, “WAN Protocols,” address specific technologies in more detail. )

说明：  实现了QPSK的调制，使用了ise自带的dds的IP核(QPSK is modulated and the IP core of DDS is used in ise.)
