ijetty服务器的启动关闭以及资源下载，基本框架，直接import进eclipse就可运行(ijetty server startup shutdown, and resources, the basic framework for direct import into eclipse can be run)

4发1收差分空时分组码系统的编码和译码程序(DSTBC coding and decoding program)

说明：  通信仿真 实现了PAM调制解调 误码率计算等等功能，有助于各方面学习(Communication simulation realizes the error rate calculation of PAM modulation and demodulation and other functions, which is helpful for all aspects of learning.)

用MATLAB产生线性跳频信号，中心频率和带宽可调(Using MATLAB to generate linear frequency hopping signal with adjustable center frequency and bandwidth)

说明：  实现了一个直接扩频系统，使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下，误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on )
