Enter and Simulink —two industry-standard platforms that have revolutionized how engineers design, simulate, and prototype digital communication systems. While MATLAB provides a script-based environment for algorithmic exploration and numerical computing, Simulink offers a graphical, model-based design framework for system-level simulation and hardware implementation.

% Modulate modSig = pskmod(data, M);
– Insert a Raised Cosine Transmit Filter with 50% roll-off. Oversample by 8 to avoid aliasing. % Compute BER [~, ber(idx)] = biterr(data, rxBits);
– Map each pair of bits to a complex symbol using the QPSK Modulator Baseband block. Set average power to 1. % Compute BER [~
– Add AWGN with desired (E_b/N_0). If modeling multipath, insert a Multipath Rayleigh Fading block before AWGN.
