STFT Implementation for Frequency-Hopping Signal Hop Period Estimation with Basic Simulation

This project implements hop period estimation for frequency-hopping signals using STFT (Short-Time Fourier Transform). The process involves simulating a frequency-hopping signal, analyzing it through STFT to obtain a time-frequency matrix, extracting the time plane, removing DC components from the time series, performing Fourier transformation, and ultimately calculating the hop period. The implementation includes key signal processing functions such as windowing, spectral analysis, and peak detection algorithms.
