% Modulate modSig = pskmod(data, M);

– Add AWGN with desired (E_b/N_0). If modeling multipath, insert a Multipath Rayleigh Fading block before AWGN. Digital Communication Systems Using Matlab And Simulink

:

– Insert a Raised Cosine Transmit Filter with 50% roll-off. Oversample by 8 to avoid aliasing. % Modulate modSig = pskmod(data, M); – Add

% Parameters M = 2; % BPSK modulation order numBits = 1e5; % Number of bits EbNo_dB = 0:2:10; % SNR range ber = zeros(size(EbNo_dB)); for idx = 1:length(EbNo_dB) % Generate random bits data = randi([0 1], numBits, 1); Oversample by 8 to avoid aliasing

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.

– Compare original bits with demodulated bits using the BER Calculator block. Export results to MATLAB workspace using an "To Workspace" block.
