In this paper, we propose new pulse-shaping techniques using raised cosine signaling instead of using conventional digital signals (rectangular waves), to reduce Inter-symbol interference (ISI) and crosstalk noise.

We show the simulation and experimental results of the raised cosine signaling scheme to show the new signaling method plays a critical part in maintaining signal integrity in high-speed VLSI systems.

Abstract:

The basic structure of Cable Digital TV Head-end System is presented in this paper. Cable Digital TV Head-end connected between the TV Signal Source and the Transmission Line is a system which can convert a variety of signal sources into a transport stream to meet the exacting standards of the transmission. The transport streams will finally be sent to service terminal by the transmitting device and the existing network. This paper gives the method of constructing Cable Digital TV Head-end System and some useful suggestions about the selection of equipment.

Abstract:

Inspired by the overlap communication theory, a new onshore radio positioning system which superimposed on terrestrial digital transmission system is proposed in this paper. This system overlaps but not affects existing terrestrial digital broadcasting.At the receiver, a reconstruction/cancellation algorithm.is implied to capture the navigation signal and positioning measurements precisely.This paper focus on the construction of overlap system,spreading navigation signal and the capture of positioning measurements.We give a method to generate spreading navigation signal and overlap with terres

Abstract:

A multi-channel wireless EEG (electroencephalogram) acquisition and recording system is developed in this work. The system includes an EEG sensing and transmission unit and a digital processing circuit. The former is composed of pre-amplifiers, filters, and gain amplifiers. The kernel of the later digital processing circuit is a micro-controller unit (MCU, TI-MSP430), which is utilized to convert the EEG signals into digital signals and fulfill the digital filtering. By means of Bluetooth communication module, the digitized signals are sent to the back-end such as PC or PDA. Thus, the patient'

Abstract:

Creation of seismic antennas involves production of a system capable to provide synchronous analog-to- digital data signal conversion of all channels and to broadcast digitized signals to the central computing complex (CCC). The article considers a structure of data transmission system from a big number of sources for application in seismic antennas. Moreover, it provides possible ways of preprocessing equipment (PE) unit arrangement in separate hermetic blocks to facilitate their replacement. Besides, the options for PE unit structural and functional schemes are offered. Application of specif
