An engineer writes a script to design a new equalizer algorithm. They use mathematical optimization to determine coefficients and plot theoretical performance limits.

The field of digital communications is the backbone of the modern connected world, enabling technologies from 5G cellular networks to deep-space telemetry. Designing these systems requires a rigorous understanding of complex mathematical principles and the ability to test algorithms under real-world impairments. MATLAB and Simulink have emerged as the industry-standard platforms for this purpose, providing a seamless environment for algorithm development, system-level simulation, and hardware implementation.

The channel represents the medium through which the signal travels. In Simulink, engineers model various impairments to test system robustness:
