Design and Implement of Multi-Antennas for High Data Rate Communication

[[abstract]]In this paper, it tries from experimental measurements to derive the required minimum antenna isolation and from using this minimum antenna isolation to have the MIMO to execute at its utmost efficiency. The issue of the minimum antenna isolation is actually the problem of pursuing the possible antenna module area of a multi-antenna system. As smaller size communication system is explored in real life the request of small size communication system has been discussed and many systems have been developed. To verify the feasibility of designing a multi-antenna and high throughput system is through the adopt of many MIMO technique implemented IEEE 802.11n 2x2 products to verify whether its throughput can be doubled. In this paper we integrate 4 2x2 AP antenna sets and under the operation of 8 antennas to attain the 1200 Mbps PHY rate through proper selection and design of available antennas, for 1200 Mbps PHY rate it is equivalently to have more then 600 Mbps throughput and with this implementation it is enable to prove the feasibility of the designed system.[[notice]]補正完畢[[incitationindex]]EI[[booktype]]紙

Analysis, Selection and Control of Optimal Driving Current Combinations in Wavelength Switching for DBR Lasers

[[abstract]]In this paper we exploit a basic type of three-stage Distributed Bragg Reflector (DBR) laser that by adjusting its input driving currents in the tri-electrode to generate signals with wavelengths that are in the International Telecommunication Union (ITU)-Band. Many driving current combinations can generate the same ITU wavelength; we will consider in this paper the situation when the input currents are restricted within certain range and to find for all those input current combinations that generate output signals with wavelengths locating in the ITU defined wavelength range. And we will through simulations to determine which set of current combinations will generate the shortest switching time. We will also propose a new current control method, when we know in advance the signal will be switched to certain band, to determine the best current switching combinations that resulting in faster and shorter switching time than that of the conventional system structure which has the drawback that it has only one fixed current combinations for each channel.[[notice]]補正完畢[[incitationindex]]EI[[booktype]]電子

Implemented LDO Chip with Output Capacitors Free

[[abstract]]In this paper the process of implementing a low dropout regulator (LDO) chip is presented; it is using uses Taiwan Semiconductor TSMC’s Manufacture Inc. 0.35um 2P4M process. The circuit designed with the described process can be is operated at 3-5V input voltage to generate 2.5V output voltage. Maximum output current can be running up to 200mA. This LDO is implemented without placing output capacitors to reduce BOM (Bill of Material) cost and stable between 0~200mA loading current and the chip is stable when the loading current is in the range 0~200mA. [8] The new proposed LDO chip can be implemented in the handheld mobile devices, battery powered equipment,wireless devices, cordless phones, or PC peripherals.[[notice]]補正完畢[[incitationindex]]EI[[booktype]]紙

Software Simulation Tool for the Capacity Analysis of WiMAX Base Stations

[[abstract]]In this paper it generate a self analysis and verification tool for the field trial data based on the simulation software in the setting of the system parameters for WiMAX base station. Through repeat reviewing and verification of the system specifications for the WiMAX system and the analysis of a series of field trial data to complete an analysis tool that has the attribute that it has been verified through field trail data. With this analysis tool it will provide the service providers a guidance of how to set up its system parameters.[[conferencetype]]國際[[conferencedate]]20091026~20091027[[conferencelocation]]Fukuoka, Japa

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
