This session will show how Model-Based Design with MATLAB® and Simulink® can be used to model, simulate, and implement communications systems. Attendees will learn how multidomain modeling with continuous verification and automatic code generation can dramatically reduce system design time. A QPSK receiver model will be used as an example to highlight the design flow.
