Data Transmission System

Abstract The paper presents the reliability estimate of the data transmission system. In practical communication solutions this type of system is widely used. A data transfer between the sender and the receiver is a complex process taking into account the human, communication system and threats. Between these components there are many relationships and dependencies. Current methods use a selective approach to this issue. Therefore, it was decided to develop and present a comprehensive assessment of the system reliability. This method has been verified in representative conditions using commercial and open source tools

Data Transmission System

The article proposes an analytical model of the functioning of the data transmission system, taking into account the influence of short-term interruptions in messages and the recovery of information distorted by cyber-attacks. The model uses the Laplace-Stieltjes transform and the Lagrange multiplier method. This helps determine the performance of switching nodes, the throughput of communication channels and their total cost in a communication system.

Wireless Fidelity

Over the years, the overdependence on Wireless Fidelity (Wi-Fi) for data transmission necessitated the need for an alternate and more reliable means of communication, hence, Light Fidelity (Li-Fi). It involves the use of Light Emitting Diode to transmit data by blinking (i.e. switching them on and off) at a speed not noticeable to the eye. This paper proposed the development of the Li-Fi system using off the shelf electronic components. This would make the system an indispensable means of communication in the nearest future. This data transmission system is different from those in existence because expensive components were not in the design, invariably reducing the overall cost of the implementation.

Modulation Methods

Galvanic coupling method has been observed to be the best method for data transmission in intra-body communication, which is proposed by Zimmerman in 1995. With the increasing transmission requirements and the development of optical fiber communication, a high speed data transmission system is required and it is possible to design an apparatus to realize the electro optic conversion. In this paper, the characteristics of the intra-body communication system are introduced. Principles and structures of the electro-optic modulation methods for intra-body communication are reviewed. Internal and external modulation methods are introduced and discussed. A system of the electro-optic and acousto-optic modulation are recommended for the intra-body communication system and discussed.

The construction of an effective intelligent information transmission system in a group of cyber-physical systems is one of the important problems in both practical and theoretical contexts. Such a system for transmitting information for a group is being built for a network consisting of separate robotic complexes. Increasingly, decentralized solutions are used to build effective interaction between group members. As a rule, in networks, decentralization is present in computing software modules, and the data transmission system between nodes is centralized. One of the aspects of such centralization is the need to send data to a specific destination directly or by relaying through other nodes - routing data in the network. In this work, a method of data transmission in a decentralized network between robotic complexes without reference to routing is proposed. The method consists of the exchange of data on the state of the entire network as a whole between the nodes.

This paper puts forward the design of communication system based on FPGA. USB controller CY7C68013 is widely used for its faster data transmission rate and diverse interface way which provide a simple and seamless connecting interface for the ATA, FPGA and DSP . This paper introduces the basic working principles of the controllers, and uses its affiliate FIFO method in order to produce corresponding control signal in FPGA with VHDL. It realizes fast data transmission between PC and FPGA through USB. Test results shows that the scheme transmission speed fast, data accurate, and can be extended to other need through the USB fast data transmission system.
