This laboratory-oriented course emphasizes the practical aspects of digital communication, offering hands-on experience with LabView and Matlab, alongside hardware experiments. The coursework incorporates fundamental signal processing techniques, various analog and digital modulation schemes, and application projects.
The course encompasses two major projects that provide comprehensive exposure to communication systems and signal processing:
-
Dual-tone Multi-frequency Signal Detection: This project involves receiving and detecting Dual-Tone Multi-Frequency (DTMF) signals, a method employed in telephony signaling, using an Arduino Uno.
-
Visible Light-based Digital Communication: This project implements a wireless digital communication system using visible light and Arduino Uno boards. The system utilizes on-off keying signal modulation and ASCII coding for message encoding, supplemented by Manchester coding to mitigate potential timing errors and offsets.
The repository includes various scripts used in projects and labs, including:
simulate_8_PSK.m: This MATLAB script simulates a digital communication system using 8-PSK (Phase Shift Keying) modulation. The script adds noise to the signal, demodulates it using a nearest-neighbor rule, and finally analyzes and visualizes the error rate of the system.
