" by (published by Bookstand Publishing ) is a hands-on guide that bridges theoretical concepts with practical simulation-driven experiments. It is designed for students and professionals to build, test, and visualize complete transmitter–channel–receiver chains. Key Topics & Features

The foundation for this work is the . It provides a vast library of over 150 Simulink blocks and more than 100 MATLAB functions, categorized for every stage of a communication link. Digital Communication Systems Using Matlab And Simulink

The platform is also integrating AI to solve complex communication problems. This includes using the alongside communications tools to create neural network-based receivers, channel estimators, and even to design new waveforms with AI. Applications like an OFDM Autoencoder for Wireless are being explored to find optimal, AI-driven transmission schemes.

Simulink introduces a graphical, block-diagram environment for model-based design. It excels at simulating dynamic systems, managing multi-rate signal processing, and visualizing time-varying waveforms. Its time-domain solver mimics real-world hardware behavior, allowing engineers to witness the sequential flow of data through a communication pipeline. Core Components of an End-to-End Digital Communication Link – Insert a Raised Cosine Transmit Filter with 50% roll-off

Adds error-correcting bits to protect data from noise (e.g., Reed-Solomon, Convolutional, or LDPC codes).

An end-to-end BPSK simulation in MATLAB can be written in fewer than 50 lines of code: It is designed for students and professionals to
