基于PRBS码型产生QPSK和16QAM信号(QPSK and 16QAM signal generation based on PRBS code)

说明：  semestrovoe PowerSupplySystem of industry plant is model in matlab

this code is represented using canny algorithm in matlab

it presence the effect of stiffness variation in active air_suspension system.

单载波频域均衡中，信道是一个很关键的问题，信道估计的好坏也直接影响系统的性能，确定一个好的信道估计序列是至关重要的，chu 序列是一种很好的估计序列(Single-carrier frequency domain equalization, the channel is a very critical issue, good or bad channel estimation is also directly affect the performance of the system to determine a good channel estimation sequence is critical, chu sequence is a good estimate of the sequence)

这是一个关于线性调频信号的产生以及其频谱分析的代码(This is a chirp signal generation and its spectrum analysis code)

arma建模，可用于时间序列分析、建模，也可用于信号处理(It is a ARMA model,it can be use in time model analy.)
