To keep things simple, we will not go into the jungle of advanced channel coding techniques. In order for a faithful reproduction and reconstruction of a bandpass analog signal with bandwidth – Fb, the signal should be sampled at a Sampling fre-quency (FS) that is greater than or equal to twice the maximum bandwidth of the signal. diagram of a communication system using Σ-ΔM is illustrated in Figure 4. Sampling Theorem mainly falls into two categories: 1) Baseband Sampling – Applied for signals in the baseband (useful frequency components extending from 0Hz to some Fm Hz), 2) Band pass Sampling – Applied for signals whose frequency components extent from some F1 Hz to F2Hz (where F2>F1), In simple terms, the Nyquist Shannon Sampling Theorem for Baseband can be explained as follows. The concepts of digital communications system design, in particular the presence of noise, cannot be conveyed with simple calculations. Are you interested in simulation of communication systems in Matlab and do not know where to start? Previous Figure Next Figure. Source Coding and Decoding: Source coding, the first block in the communication system architecture shown in Figure 1, is the process of encoding information using lesser number of bits than the uncoded version of the information. Source coding, the first block in the communication system architecture shown in the previous figure, is the process of encoding the information using lesser number of bits than the uncoded version of the information. . The corresponding decoding technique in the receiver uses the redundant information in the codeword and tries to restore the original information, thereby providing immunity against the channel noise.

Bookstand Publishing 2016, ISBN 978-1-58909-621-9, 261 pages Here you will find additional materials for using the digital communication simulation with MATLAB and Simulink in undergraduate, graduate and continuing professional education. The book discusses digital Fourier transforms (FT), FT-based operations, multiple methods of wave-optics simulations, sampling requirements, and simulations in atmospheric turbulence. Source coding attempts to compress the data to improve bandwidth utilization, whereas, channel coding attempts to add redundancy to the data to make it more reliable (which reduces data rate) and therefore more robust against the channel noise. For example mobile phones are operated in a very noisy environment in which the noise sources may be one or more of the following: interference from other mobile users, ignition noise, thermal noise, multipath interference and other man made noises. It is important to bear in mind that the correction and detection of errors are not absolute but rather statistical. * Will there be any deviation if the signal is converted back to analog domain?

Obviously data has to be sent over a long distance through any media used for/by the communication system. MATLAB/Simulink-Based Software-Defined Radio Laboratory . Let’s consider the following logical questions: * Given a real world signal, how do we select the sampling rate in order to faithfully represent the signal in digital domain? Digital Modulations using Matlab is a learner-friendly, practical and example driven book, that gives you a solid background in building simulation models for digital modulation systems in Matlab. The digital modulation schemes such as M-PSK (M-ary Phase Shift Keying) and M-QAM (M-ary Quadrature Amplitude . Two of them are listed here. This program simulates a basic communication system using Matlab, and it plots BER curves in order to compare the performance of several codification algorithms. The following sampling theorem is the exact reproduction of text from Shannon’s classic paper [Shannon1949], "If a function f(t) contains no frequencies higher than W cps, it is completely determined by giving its ordinates at a series of points spaced 1/2W seconds apart.". Any of the above conditions can be waived if you get permission from the author. This volume is focused on applications, but it also provides a good presentation of the principles.

Found insideThe book presents an integrated treatment of continuous simulation with all the background and essential prerequisites in one setting. Channel coding is a technique to make the transmitted data robust to such noises, meaning that you can still recover your data (using a Channel Decoder) intact even if it is corrupted by certain amount of noise.
