Principles of Communication

$

• The communication process: Sources of information, communication channels, modulation process, and communication networks • Representation of signals and systems: Signals, Continuous Fourier transform, Sampling theorem, sequences, z-transform, convolution and correlation. • Stochastic processes: Probability theory, random processes, power spectral density, Gaussian process. & • Modulation and encoding: %

' Basic modulation techniques and binary data transmission:AM, FM, Pulse Modulation, PCM, DPCM, Delta Modulation • Information theory: Information, entropy, source coding theorem, mutual information, channel coding theorem, channel capacity, rate-distortion theory. • Error control coding: linear bloc codes, cyclic codes, convolution codes &
