阵列信号处理领域的基于Lcmv准则的波束形成方法，对初学者有用。(Array signal processing based on the criteria Lcmv beamforming method, useful for beginners.)

DPSK系统的调制解调仿真，包括原理以及源代码和仿真结果，十分完整，包含了DPSK的相干解调，非相干解调，有自己的许多心得，希望对初学者有帮助(Modulation and demodulation of DPSK system simulation, including schematics and source code and simulation results, very complete, contains DPSK coherent demodulation, non-coherent demodulation many experiences, hope helpful for beginners)

对一个信号进行奇异值分解，根据差分谱最大值点，重构信号，达到降噪的目的。(Signal for a singular value decomposition, according to the differential spectrum maximum point, the reconstructed signal to achieve noise reduction purposes.)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)
