用Visual C++的API函数来打开、关闭串口和设置串口通讯速率等功能。(Visual C++ using the API function to open and close the serial port and set up features such as serial communication rate.)

在实际的调谐解调电路中，采用的是非相干载波解调，本振信号与发射端的载波信号存在频率偏差和相位抖动，因而解调出来的模拟I、Q基带信号是带有载波误差的信号。这样的模拟基带信号即使采用定时准确的时钟进行取样判决，得到的数字信号也不是原来发射端的调制信号，误差的积累将导致抽样判决后的误码率增大，因此数字QPSK解调电路要对载波误差进行补偿，减少非相干载波解调带来的影响。(In the actual tuning and demodulating circuit, non-coherent carrier demodulation is adopted, and the frequency deviation and phase jitter of the local oscillator signal and the carrier signal of the transmitting end are present, and thus the demodulated analog I and Q baseband signals are signals with carrier error.)

又一个利用网上寻呼提供商的web页面来发送网上寻呼的程序，可以支持很多提供商。(Another program which uses web pages of internet call provider to send internet calling , and supports many providers)

高动态模型，加加速度，加速度和速度都可以改变，仿真出多普勒频偏变化和相位变化。(High dynamic model of acceleration, acceleration and speed can be changed, the simulation of doppler frequency and phase changes.)

turbo码的matlab仿真源程序,比较详细,包你满意()

for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X Y Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies Please validate this function before using it
