Analysis and Simulation Model of Physical Carrier Sensing in IEEE 802.11 Mesh Networks

利用vc++实现的一个直接序列扩频通信处理程序，包含了简单的测试数据。此程序很详尽。(Using vc++ to achieve a direct sequence spread spectrum communication processes, including a simple test data. This program is very detailed.)

说明：  线性调频信号的仿真，在此基础上，结合频控阵，实现了频控阵和线性调频信号的结合，将结合后的信号作为欺骗干扰信号。(Based on the simulation of LFM signal, the combination of frequency control array and LFM signal is realized, and the combined signal is regarded as deceptive jamming signal.)

说明：  MIMO-OFDM仿真，包含Jakes模型生成信道、信道编码、ZC序列生成和OFDM四个子文件(Simulation of MIMO-OFDM)

In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization is an essential procedure for normal operation of the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.

说明：  turbo码的c语言程序，使用c语言来完成整个turbo码的编解码过程，并且程序后附带比较详细的解释(turbo code c language program, use c language to complete the entire turbo code codec process and procedures attached to explain it in more detail)

performance evaluation of reactive and proactive protocols. the performance is evaluated with respect to throughput over TCP and UDP connections types

这是看完一本通信仿真手册后我自己写的一点程序，包括ASK FSK PSK的调制和解调程序，不过是比较简单的 ，因为用了公式的()
