PROGRAM OVERVIEW

Description

Communications is the field of study concerned with the transmission of information through various means. It can also be defined as the technology employed in transmitting messages. It can also be defined as the inter-transmitting the content of data (speech, signals, pulses, etc.) from one node to another.
            Analog communication is a communication method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. It could be the transfer of an analog source signal using an analog modulation method such as FM or AM, or no modulation at all.
            Digital communication is the physical transfer of data (a digital bitstream) over a point-to-point or point-to-multipoint transmission medium. Examples of such media are copper wires, optical fibers, wireless communication media, and storage media. The data is often represented as an electromagnetic signal, such as an electrical voltage signal or an infra-red signal.
            Analysis and design of analog and digital communication systems based on Fourier analysis. Topics include linear systems and filtering, power and energy spectral density, basic analog modulation techniques, quantization of analog signals, line coding, pulse shaping, and transmitter and receiver design concepts. Applications include AM and FM radio, television, digital communications, and frequency-division, and time-division multiplexing.

What will you learn?
1. Analyze the performance of a baseband and passband digital communication system in terms of error rate and spectral efficiency. 
2. Perform the time and frequency domain analysis of the signals in a digital communication system.
3. Select the blocks in the design of the digital communication system.
4. Analyze Performance of spread spectrum communication system.

Prerequisites
Prerequisites required for the communication system are basic knowledge in system analysis using convolution, Fourier transforms and series, Laplace transforms, and frequency response.
