The power of digital signal processing can probably be best appreciated in the enormous progresses which have been made in the field of telecommunications. These progresses stem from three main properties of digital processing: • The flexibility and power of discrete-time processing techniques, which allow for the low-cost deployment of sophisticated and, more importantly, adaptive equalization...

In an environment such as underwater channel where placing test equipments are difficult to handle, it is much practical to have hardware simulators to examine suitably designed transceivers (transmitter/receiver). The simulators of this kind will then allow researchers to observe their intentions and carry out repetitive tests to find suitable digital coding/decoding algorithms. In this p...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

The Objective of this paper is to demonstrate the application of “Mathematical Algebraic Coding Techniques” in quest of achieving “Reliable Digital Data Communication Systems”. Environmental interference and physical defects in any digital data communication system can cause random bit errors during data transmission. As the signal is transmitted through a communication system, the signal gets ...

This study develops a form of digital baseband Intra-Body communication for wideband transmission. A simplified circuit model of signal and noise is constructed to analyze the contribution of the high pass filter function of the electrostatic coupling Intra-Body communication system to wideband digital transmission in electrostatic coupling Intra-Body communication. A unit step function is pres...

In digital communication system, digital information can be sent on a carrier through changes in its fundamental characteristics such as phase, frequency and amplitude. The use of a filter plays an important part in a communication channel because it is effective at eliminating spectral leakage, reducing channel width, and eliminating interference from adjacent symbols (Inter Symbol Interferenc...

Today’s and future communication systems in maritime rely on digital data communication between the ship and transceivers that are either on land, in air (satellite) or on sea. Analog voice communications is not an integrated part of future maritime communication system proposals. However, it is in general preserved in its functionality according to future maritime communication system proposal...
