To improve data transmission performance of the data acquisition card, a design of high-speed data transmission system is proposed in the thesis. Using FPGA of programmable logic devices, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission method is implemented in FPGA. Eventually the design implements the data transmission with high-speed through PCI Express interface. Through simulation and verification based on hardware system, this design is proved to be feasible and can satisfy the performance requirements of data transmission in the high-speed data acquisition card applied in high-speed railway communication. The design also has some value of application and reference for a universal data acquisition card.

Differential Transmission

In radio communication systems, when implementing coherent types of reception, it is assumed that the receiver knows information about the state of the communication channel, which is achieved by introducing signal redundancy (pilot signals). The frequency of sending pilot signals depends on factors that change the state of the communication channel, one of which is the high speed of movement of mobile stations. The use of pilot signals not only hinders the efficient use of the radio frequency resource, but also, in the case of fast fading, does not allow the channel to be estimated and tracked with the required accuracy. These disadvantages can be eliminated by using the differential transmission method, for the implementation of which there is no need to know information about the state of the channel. The application of the principles of differential transmission to space-time coding does not find sufficiently effective solutions that combine low computational complexity and energy efficiency of differential coding methods.

High Data

In industrial fields such as seismic explorations, RS485 is considered a workhorse interface standard, and it is the most widely used for serial interface found on sensors. However, long-distance transmission at high data throughput is one of the key features. An improved RS485-based high-speed remote transmission method is developed to implement the transmission of large amounts of data from distributed sensors. Based on the signal integrity analysis, the hardware interface designs including interface chips and impedance matching are determined by continuous square-wave pulse transmission. Then a self-defined protocol with the aid of FPGA hardware real-time processing is designed to make high-speed clock recovery and frame synchronizations. The 8b/10b encoded data streams are transmitted via a twisted-pair cable in the experiment. The experimental results indicate that the designed RS485 transceiver unit can drive the 220 meter twisted-pair lines at 20Mbps data speed with an error rate of 10-11.

AbstractVisible Light Communications (VLC) is considered as an emerging technology for indoor wireless communications to achieve high-speed and secure data transmission. Instead of using radio frequency (RF) spectrum, VLC uses the visible light spectrum to perform lighting and communications functions simultaneously. Multiple access points VLC (multi-AP VLC) networks use ceiling access point (ceiling-AP) and desk access point (desk-AP) to provide both uniform and spot lighting in order to achieve full coverage and high spectral efficiency. Because mobile user equipment (UE) require seamless connectivity when moving, fast link handover between VLC access points (VLC-AP) has to be supported in the VLC networks. In this paper, we present a coordinated multi-channel transmission method (CMcT) used to improve quality of service (QoS) of cell-edge UEs and propose a novel proactive link handover scheme deploying the CMcT method for multi-AP VLC networks. Performance results obtained by computer simulation show that the proactive link handover scheme deploying the CMcT method can significantly improve user throughput and packet delay comparing with those of other link handover schemes.

The purpose of the article is to present the evolution of television networкs and services and streaming them through analogue TV to full digitalization to the introduction of IP technology and advanced smart smart equipment. The networкs of cable TV operators are being transformed into triple play networкs, кnown as triple play. In addition to standard television, they also carry telephony and the Internet. As a result, it can be considered that the equipment converges and becomes more intelligent and highly functional. To date, networкs are switching to the IP core and offering high-speed and broadband IP services. Television is undergoing its metamorphosis and is being transformed to IPTV - (Internet Protocol TeleVision). The authors' contributions are related to the analysis of the main components and processes for the acquisition and processing of television content in IPTV.
