This MATLAB script simulates M-ary Quadrature Amplitude Modulation (M-QAM) transmission over an AWGN channel using Root Raised Cosine (RRC) pulse shaping. It plots ...
This study evaluates three channel estimation techniques—MATLAB's built-in LS-based estimator, standalone LS, and MMSE—within the IEEE 802.11 Wi-Fi standard. Simulations in Rician and AWGN channels ...
Abstract: Low-Density Parity-Check (LDPC) codes are essential for error correction in space communications, particularly in CCSDS implementations. Space communication ...
