Beyond the basics, MATLAB and Simulink are used to simulate advanced techniques that are the backbone of modern wireless standards like 5G, Wi-Fi (802.11a/n/ac/ax), and LTE. for idx = 1:length(EbNo_dB) % Generate random bits

In the world of digital communications, the leap from abstract signal processing theory to a working hardware prototype is notoriously steep. Mathematical equations for modulation, channel coding, and equalization rarely translate cleanly into real-time C code or FPGA logic on the first attempt. Enter —the industry-standard ecosystem for closing this gap.
