Resource Overview
Detailed Documentation
This document provides a detailed analysis of signal-to-noise ratio characteristics for various signal types including linear frequency modulated (LFM) signals, nonlinear frequency modulated (NLFM) signals, continuous wave (CW) signals, frequency-coded signals, and phase-coded signals. The implementation includes MATLAB code for generating these signals using chirp functions for LFM, custom phase modulation for NLFM, and coding sequences for frequency and phase-modulated signals. We also share practical programs featuring SNR calculation algorithms that utilize power spectral density analysis and noise floor estimation techniques, which we hope will be valuable for researchers and engineers working in signal processing applications.
