只要输入信号的中心频率和带宽，自动生成带通滤波器采样率、信号保护带、采样率误差容限(Just enter the center frequency and bandwidth of the signal, automatically generated bandpass filter sample rate, signal protection zone, the sampling error margin rate)

U盘控制芯片CH331,CH331 是一个小容量U 盘的控制芯片，只要外加一个串行存储器芯片，就可以实现2KB 到512KB 的小容量U 盘。(U disk controller IC CH331, CH331 is a small-capacity USB control chip, As long as plus a serial memory chips, we would achieve 2 KB to 512 KB of small U disk capacity.)

说明：  罚函数法的Matlab程序设计的相关程序，不一定能运行有些错误可能(external penalty function method)

用于解决最短路径问题的算法被称做“最短路径算法”， 有时被简称作“路径算法”。 最常用的路径算法有： Dijkstra算法(The shortest path algorithm is used to solve the problem is called the " shortest path algorithm," sometimes referred to as a " path algorithm." The most common path algorithm: Dijkstra algorithm)

GPS信号跟踪与捕获，相关及非相关累积算法(GPS signal tracking and capture, accumulation-related and non related algorithms)

自己编写的载波恢复算法仿真程序，一直在用，性能很好(carrier_recovery source code based on matlab)

说明：  里面有8PSK，GMSK的matlab源程序，贡献出来了(I was interested in the theory for 8PSK and came across this m-file written in 1999. It requires 2 function calls (graymapPSK and grayunmapPSK) which I have included and must be uncommented(single comments only) and loaded into your workspace. Remove the function calls from this m-file after you load into your workspace. It seems to work well and give valid results for BPSK and QPSK but I have a question about the setup for 8PSK and the solution for Pseint where Pse=Pseint. Also, the Gray coding seems different than what I m used to. Some of you more theoretical minded may have some insight into the theory behind how Pseint was determined and comment. I don t have the communications toolbox-blockset and was wondering how it compared with Matlab s example simulation of 8PSK with Gray coding (in Simulink?) Each run takes about a minute and the loop iterations are shown in the command window. A numerical example of a satellite link is shown using uncoded QPSK )
