Simulation of signal energy detection algorithm based on MATLAB
Signal energy detection is a commonly used signal processing technology used to determine whether a signal exists or to evaluate the quality of a signal. In this article, we will introduce how to use MATLAB to implement the signal energy detection algorithm and provide the corresponding source code.
Signal energy is the total power of a signal over a certain period of time and is usually calculated by squaring the signal and summing it. In the signal energy detection algorithm, we divide the signal into multiple windows and perform energy calculation on the signal within each window. According to the energy threshold determination rule, we can determine whether the signal exists.
The following is a sample code for a signal energy detection algorithm based on MATLAB:
% 生成示例信号
fs = 1000; % 采样率
t = 0:1/fs:1; % 时间向量
f = 10
