伪随机码的模糊函数程序，同时画出模糊函数图，零时延，零多普勒以及等高线图(Ambiguity function of pseudo-random code procedures, and plans to draw fuzzy function, zero delay, zero Doppler and the contour map)

QPSK的调制；比较DQPSK和QPSK在通过加性高斯白噪声信道时的误码性能；OFDM系统(QPSK modulation more DQPSK and QPSK in additive white Gaussian noise through the channel bit error performance when OFDM system)

matlab编写的盲信道估计程序，对进行信道估计的朋友有用。(matlab prepared blind channel estimation procedures, the channel estimation friends helpful.)

matlab教材附带的代码 可以运行.关于通信方面的仿真。(the matlab code about communitinication)

说明：  输入为两个信号，采用music算法进行特征分解，实现测向的目的(Input into two signals characteristic decomposition algorithm using music to achieve the purpose of finding)

The QSystemSemaphore class provides a general counting system semaphore for Linux.

本程序实现了kalman滤波和在坐标和速度上的误差计算(This procedure implements the kalman filter and the coordinates and speed of calculation errors)

说明：  完整的带通采样定理验证程序,含测试用例,望对大家有用.(Bandpass sampling theorem complete verification process, including test cases, hope for all of us. )
