跳频扩频系统仿真

用API函数集写串口通信程序-API Function Set write serial communication program

ZTE s ME3000 GSM module technical specifications, included pin out diagram of the module, power supply reference design and hardware spec.

模拟通道的通信过程，能够进行正常的输入输出操作-Analog channels of communication process, to carry out the normal operation of the input and output

在四径信道条件下，仿真Ofdm调制通信系统的误码率曲线图-At four-path channel conditions, the simulation of communication systems Ofdm modulation bit error rate curves

是对简单aloha 以及csma 二进制指数退避的仿真，根据节点数以及到达率的变化，可以得到不同的系统吞吐率，成功概率以及延迟。是本人所写，可以调节窗长以及对退避算法尽心改进。比较有用。

服务端一方面对图像进行采集压缩传送，另一方面接受网络传送过来的运动控制指令。客户端一方面负责接受图像数据，并解压后显示，另一方面发送用户界面操作所产生的运动遥控信息。

中文RFC文件，无需翻译，对学习很有帮助！

These mobility generator tools are used to generate a rich set of mobility scenarios used to evaluate the protocol performance in Mobile Ad Hoc Network. The tools include the Reference Point Group Mobility(RPGM) model, Freeway Mobility Model and Manhattan Mobility Model.

A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;
