Phase Encoding Signals with BPSK and QPSK Implementation

This repository contains complete source code for generating various radar signals including phase encoding (with binary BPSK and quadrature QPSK modulation), Linear Frequency Modulation (LFM), Nonlinear Frequency Modulation (NLFM), Pulse Amplitude Modulation (PAM) signals, and frequency-encoded FSK signals with additive noise. The implementation employs digital signal processing techniques using MATLAB/Python, featuring key functions for waveform generation, modulation schemes, and noise injection algorithms. The codebase serves as an excellent program resource for producing diverse radar signals through modular signal generation components. Implementation details include constellation mapping for PSK modulation, chirp signal synthesis for LFM/NLFM, and amplitude coding for PAM signals. Future enhancements could incorporate additional signal sources such as Phase Shift Keying (PSK) variants, Quadrature Amplitude Modulation (QAM), and continuous wave signals to provide more comprehensive radar signal generation capabilities. Program optimization considerations include computational efficiency improvements through vectorized operations, accuracy enhancements via oversampling techniques, and adaptability for different application scenarios through parameterizable signal specifications.
