用VB编写的串口调试助手，附带51程序，大家可以学习，很经典，很地道(With VB serial debugging assistant, with 51 programs)

说明：  对2ask、2psk、2dpsk、2fsk的调制仿真(Modulation simulation of 2ASK, 2PSK, 2DPSK and 2FSK)

说明：  载波同步仿真，使用的是反馈补偿法，接收信号经补偿矩阵，误差提取，环路滤波，相位累加器后反馈回补偿矩阵，稳定后估计相位趋近相位差，存在相位模糊情况。(the simulation of the carrier synchronization)

用c语言写的ldpc码的最小和算法译码程序。(The codes are about ldpc decoding,using min-sum algorithm by c++.)

FreeSender 群发器，学习socket 编程(FreeSender mass learning socket programming)

说明：  一种PC与单片机多机RS232串口通信设计应用(A PC with a single-chip multi-machine RS232 serial communication design application)

c#编写串口通讯代码 多线程实现,老外写的，很有用，很全面(c# write serial communication code multithreading, written by foreigners, very useful, very comprehensive)

这是一篇基于循环延迟分集的分组预编码和空时频编码技术方面的典型文章(This is a cyclic delay diversity based on the group pre-coding and space-time-frequency coding technology, a typical article)

网络仿真软件OPNET AdHoc模型文件(network simulation software OPNET TCP model document)

MPSK QAM MASK MPSK信号载频估计matlab程序(matlab program of estimating Carrier Frequency of MPSK QAM MASK MPSK signal )
