LABS Infrastructure

Communication Engineering Lab

The communication Systems Laboratory intends to cover the basic understanding of functionalities of various block-sets involved in communication system. It involves system design and simulation exercises using MATLAB and Simulink and experiments based on HW boards. Students are introduced to the functioning of modern communication systems and how they perform in the presence of noise.

The essence of any communication system is the generation and reliable detection of signals which carry information over a noisy channel with bandwidth and power limitations. A distinction is usually made between analog and digital communication systems depending on whether the transmitted information in digital or analog form. Most physical channels, such as wires, optical fibers or free-space electromagnetic wave propagation are analog in nature and must use waveforms (which are continuous in time and amplitude) at their inputs and outputs. Modern communication systems use digital signal processing to produce baseband waveforms at the transmitter and to process them at the receiver. Analog hardware is then used for modulation and demodulation, i.e. for moving the signal between the lower frequency baseband and the higher frequency passband where the actual communication takes place. In analog communication laboratory basic experiments like analog modulation techniques, sampling theorem, time division multiplexing are present and in digital communication laboratory some digital modulation technique experiments, pulse code modulation, delta modulation, channel coding experiments are present.
