The increasing use of digital components in closed-loop RF control systems requires a uniform interface for fast exchange of information between subsystems. The main requirements for such a communication system arise from large distances between the peers (up to several hundreds of meters), high data rates and short and predictable delays. Optical fibers in combination with Field Programmable G...

-Chaotic system are unstable and a-periodic ,making them naturally difficult to identify and to predict .This nonlinear , unstable and a-periodic characteristics of chaotic signals has numerous features that make it attractive for communication use. This field of communication is termed as chaotic communication. Chaotic communication signals have large bandwidth and have low power spectrum dens...

A Picture Archiving and Communication System (PACS) will operate in a hospital and provide a totally digital environment for storing and retrieving medical images, diagnostic reports, and patient data [1]. Generally speaking, a PACS consists of a communication network and three types of network nodes: imaging equipment, viewing workstations and database archive system. Imaging equipment nodes a...

Visual communication systems can exploit the advantages of analog transmission and digital compression: Analog transmission allows the quality of the recovered data to vary gracefully as the channel conditions vary, whereas digital compression allows for powerful data reduction. In this paper, a system optimized for bandwidth-and power-limited channels which combines analog and digital communic...

− In this paper, performance of OFDM digital communication systems have been analyzed with improved ICI cancellation technique. The bit error rate has been regarded as a fundamental information theoretic measure of a communication system. A novel parallel ICI cancellation technique has been proposed for mitigating frequency offset of OFDM digital communication systems. The simulated results of ...

Wireline and wireless communication devices (modems – DSL and cable and WiFi – and cellular radios) are the workhorses that drive the modern information age. Their central goal is to move around the basic digital currency of the information: bits. This movement is done on physical media, either via wires or via wireless. The key challenge is that the input-output relationship of the physical me...

Over the last decade, the “digitization” of the electron enterprise has grown at exponential rates. Utility, industrial, commercial, and even residential consumers are transforming all aspects of their lives into the digital domain. Moving forward, it is expected that every piece of equipment, every receptacle, every switch, and even every light bulb will possess some type of setting, monitorin...

In wireless, satellite, and space communication systems, reducing error is critical. High bit error rates of the wireless communication system require employing various coding methods on the data transferred. Channel coding for error detection and correction helps the communication system designers to reduce the effects of a noisy transmission channel. The purpose of this paper is to study and ...
