java源码,主页制作百宝箱,收集了几十多种主页制作常用的JAVA和javascript特效(Java source code, homepage making kit, collected dozens of various homepage making commonly used Java and javascript effects)

485通讯程序，有需要的看看啦，哎怎么要20字啊，真是的(IT IS A 485 COMMUNICATION FOR 28335)

瑞利衰落信道建模 误码率、传输速率 多径传输(Rayleigh fading channel modeling Bit error rate and transmission rate Multipath transmission)

通过调用计算雷达的信噪比，对比雷达在三咱不同雷达截面积下的信噪比，从而分析不同雷达截面积下信噪比情况是如何的，得出相应结论(Calculated by calling the radar signal-to-noise ratio than radar signal-to-noise ratio in the three Zan different radar cross section, which is how to analyze the signal-to-noise ratio in a different radar cross section, draw the corresponding conclusions)

说明：  非常好的OPC服务器源代码 免费的 没有时间限制(Very good OPC server source code for free no time limit)

生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)

Gardner位同步算法与锁相环的联合仿真程序.加入了时偏和频偏，能很好地锁定时偏和频偏，得到最佳采样输出。(Gardner bit synchronization algorithm and phase-locked loop joint simulation program, adding time offset and frequency offset, can well lock the bias and frequency offset, get the best sampling output.)

wireless communication channels model

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)

次程序用来仿真叠加了地杂波和高斯白噪声的回波信号(Second program is used to simulate the ground clutter superimposed Gaussian white noise and the echo signal)
