QPSK Modulation and Demodulation with Serial-to-Parallel Conversion, Fourier Transforms, Channel Estimation (LS Criterion), and Doppler Shift
This MATLAB implementation covers QPSK modulation and demodulation, including serial-to-parallel conversion, Fourier transforms and inverse transforms, channel estimation using Least Squares (LS) criterion, and Doppler shift compensation modules with clear code demonstrations and algorithm explanations.
