QPSK_BER_Es

This paper presents the simulation of a simple First Order plus Delay Time (FOPDT) process model using advanced control algorithms. Specifically, these advanced algorithms are the IMC-based PID controller, the Model Predictive Controller (MPC) and the Proportional-Integral-Plus Controller (PIP) and their performance is compared with the conventional Proportional – Integral – Derivative (PID) algorithm. The simulations took place using the Matlab/Simulink™ software.

利用stft实现了跳频信号的跳周期估计 简单的进行了跳频信号的仿真，然后利用短时傅里叶变换对跳频信号进行分析，再对得到的时频矩阵提取时间平面，对时间序列去直流，进行傅里叶变换，最后实现得到跳周期。(estimates the hopping time of the sfh by stft )
