Novel digital techniques to improve the sensitivity of limiting amplifier

[[abstract]]In this paper we utilize the novel digital techniques (TW, DRMC, DS) to improve the sensitivity of the limiting amplifier. The Time Window (TW) technique can ignore the positive and negative trigger noises within the window close time. The Delay Racing Memory Counter (DRMC) technique can eliminate the positive trigger noises within the window open time. The Delay Sum (DS) technique can solve the negative trigger noise around the signal transition from low to high. The experimental results are also presented[[notice]]補正完畢[[conferencetype]]國際[[conferencedate]]19990726~19990728[[iscallforpapers]]Y[[conferencelocation]]Poerto Vallarta, Mexic

Intelligent Safety Warning and Alert System for Car Driving

100學年度研究獎補助論文[[abstract]]The new vehicle performance has been continuously improved and the study results relating to the safety of car driving have also been continuously reported and demonstrated, it is trying to find a balance point between the development of vehicle speed limit and the protection of driver's safety. In the current study and development of various products, no matter it is in the enforcement of vision system, radar detection or the tracing and control it is always asking the driver to watch or handle the possible issues after the occurrence of accidents. In this paper we try to develop a system to provide the prior to accident information to the vehicle control unit so that it enables the vehicle to prevent the happening of accident. During the vehicle movements the system will continuously record the vehicle's moving status and conditions so that the record will provide the decision basis in the accident investigation if it unfortunately happens the fatal accident.[[notice]]補正完畢[[journaltype]]國際[[incitationindex]]EI[[booktype]]紙本[[countrycodes]]TW

The measurement and analysis of WiMAX base station signal coverage

[[abstract]]This paper presents the field trial measurement data of WiMAX base station; it includes the system coverage, signal strength and available transmission rate. Data consisting of real time images, VoIP internet telephone are transmitted through Skype software by using WiMAX, HSDPA (3.5G) and EDGE (2G) transmission techniques, and these data are connected to centrally equipped wireless monitoring servers to perform data monitoring and analysis. Finally, we make comparisons, analysis and discussions of these three transmission techniques from the measured and characterized data.[[incitationindex]]EI[[booktype]]線上

Applying Genetic Algorithms to the Data Traffic Scheduling and Performance Analysis of a Long-Term Evolution System

[[abstract]]In this study it develops a superior transmission resource allocation method by using genetic algorithm. The convergence properties of genetic algorithm are employed to increase the transmission resource use efficiency of a base (station) to allow users to access wider bandwidth and to improve the system throughput and packet service rate. In this paper, it also studies the genetic algorithm convergent phenomena. The calculated system convergent time is significantly less than that of a long term evolution (LTE) frame duration. Finally, the system performances with and without implementing the genetic algorithm in resource allocations are simulated; their performances are compared to study the effectiveness of using the genetic algorithm in resource allocation.[[notice]]補正完畢[[booktype]]電子

Using hopping technique for interference mitigation in Modulated Scattering Array Antenna system

[[abstract]]In modulated scattering antenna array (MSAA) system it has at the receiver side encountered low levels of scattering signals [1,2] and interferences in addition to the desired signal. In this paper, we propose to utilize the frequency hopping scheme to improve the performance of scattering signals under the influence of narrow band strong interferences. From the numerical results, it concludes that with larger hopping range it improves the ability of anti-interference effects.[[incitationindex]]SCI[[incitationindex]]EI[[booktype]]電子
