说明：  面阵中的DOA估计，利用ESPRIT进行估计(DOA estimation in plane array is performed by ESPRIT)

传统的MVDR算法上加约束能够产生宽零陷，从而抑制动态干扰(In traditional MVDR algorithm, adding constraints can produce wide nulls, thus restraining dynamic interference)

对原始信号进行小波包分解，小波函数及分解尺度均可自调(The original signal is decomposed by wavelet packet, and the wavelet function and decomposition scale can be adjusted automatically)

对2*2瑞利衰落BQSK调制的MIMO信道进行均衡，对比ZF、MMSE、ML方法的均衡效果。(Script for computing the BER for BPSK modulation in a Rayleigh fading channel with 2 Tx, 2Rx MIMO channel with MMSE、ZF、ML equalization.)

说明：  BOC调制的Matlab程序仿真及Simulink模型(Matlab program and BOC modulation simulation model of Simulink)

说明：  qpsk基带调制和解调matlab程序，包括gardner位同步(qpsk modulate and demodulate in baseband use matlab code,including gardner time synchronization)

说明：  以均匀圆阵为例，通过功率倒置算法，使特定方向上的天线增益最大，已达到波束成形，空域滤波的目的 参考文献《GNSS空域抗干扰算法研究及FPGA实现》(Research on Spatial Anti-jamming Algorithms of GNSS and FPGA Implementation)

说明：  51MODBUS从机程序源码希望对有用的人有用，，(51MODBUS,welcom to here,thank you very mouch.)

Z域表示的数字滤波器的响应举例,利用给出的Z域的传递函数，求在给定初始状态和输入信号的情况下的系统的零输入响应，零状态响应，完全响应等。(Z-domain representation of the response of the digital filter for example, using the given Z-domain transfer function, to seek zero input response of the system in the case given the initial state and the input signal, the zero state response, complete response.)
