FAST ACQUISITION ALGORITHM FOR HYBRID DS/FH RECEIVER

Bo, Zhang, Yixun, Ren, Dongkai, Yang, Qishan, Zhang 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper introduced a fast scanning and waiting acquisition method for a DS/FH receiver used in the telemetry field. Mathematic model of the hybrid DS/FH system’s acquisition process is given and discussed. The average acquisition time expression using this method and generalized average acquisition time formula is derived also. The validity of the proposed algorithm is verified after simulation. In the circumstances of Additive Gauss White Noise for the channel, simulation result at Ec/N0= -15dB shows that the average acquisition time is decreased almost 4 times than that of waiting and searching method.

TELEMETRY DESIGN FOR A BOBSLED ANALYSER

Chyr, Y-H., Jordan, M., Hagedorn, M., Han, B., Pat, J., Ting, S., Trotman, T. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / This paper was prepared as part of the team design competition for a graduate level course given at the University of Canterbury, in Christchurch, New Zealand. It presents a high level design of a bobsled data acquisition system which is intended to aid athletes and coaches in achieving the maximum benefit from their time at the bobsled track. The system will measure every applicable aspect of the bobsled’s performance down the track, and provide real time and near real time feedback for the athletes and the coach. This system implements an inertial navigation and position system, monitors wind speed, measures the drivers steering input and effort, measures individual pushing effort in the critical start stage of the run, and provides cue signals to the runners when to mount the sled. A robust packet format and error correction in conjunction with a E2ROM backup system ensure data integrity. The data is transmitted utilising a GMSK signalling scheme, operating at a frequency of 400MHz. A space conserving patch antenna is mounted on the bobsled and a leaky wave antenna placed alongside the track for the transmission system. A link budget and the error performance of the transmission system are analysed. A graphical front end at the coach’s base station provides real time data display and analysis.

The Realization of a Digital Correlation Detector of Telemetry Frame-Synchronization-Pattern Using a Neural Network

Jun, Zhang, Yi, Qiu, Yan, Du, Qishan, Zhang 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / In this paper, a method for digital correlation detector that takes advantage of the frame-synchronization-pattern feature of coincidence rate and adopts a multiple-bit detection window is proposed. Based on this method, a new digital correlation detector with a neural network is designed. It can recognizes frame-synchronization-pattern with error bits and slippage bits correctly, which has been approved practically according to the experimental results.

A DISTRIBUTED, LOW-POWER TELEMETRY SYSTEM FOR SOLAR RACE CAR APPLICATIONS

Tuomey, E. S., Velasquez, G., Slade, S., Bunker, K., Reyes, E., Yousefnejad, T. 10 1900 (has links)
International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / This student paper was produced as part of the team design competition in the University of Arizona course ECE 485, Radiowaves and Telemetry. It describes the design of a telemetry system for the University of Arizona’s Daedalus solar car. This is a distributed, low-power, telemetry-on-demand system that solves many of the problems typically encountered in this specialized telemetry application. The topology of the distributed microcontroller system is shown, as are optimal command and data packet structures. Also featured is a high-gain, low profile antenna system designed specifically for the solar car. Additionally, a customized chase car operator interface is illustrated.

DESIGN OF AN ANIMAL TRACKING AND TELEMETRY SYSTEM

Avery, H., Choi, Y., Clyne, M., Irie, K., Kong, J., Lineham, A., Pascoe, P., Zaidi, A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper was prepared as part of the team design competition for a graduate level course given at the University of Canterbury, in Christchurch, New Zealand. It presents a high level design of an automated telemetering system for tracking and monitoring a number of land-based animals as small as a rabbit. The primary purpose of the system is to monitor both desirable and undesirable species of wildlife in the New Zealand bush in order to better understand their living habits and environmental requirements. The typical conditions monitored are body temperature, moisture levels, light intensity, physical activity, and heart rate. All critical aspects of the telemetering system have been specified, including the sensors, transmitter/receiver, and telemetry packet and frame design. A calculation of the link budget for the system has been performed.

DESIGN OF A SNOW AVALANCHE TELEMETRY SYSTEM

Lim, C., Hardie, S., Lyness, A., McMillan, S., Ung, L., Yu, V. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper was prepared as part of the team design competition for a graduate level course given at the University of Canterbury, in Christchurch, New Zealand. It presents a high level design of a snow avalanche telemetry system. The goal of the system is to provide data to better assess avalanche risk, and to assist in designing more effective protection measures in avalanche prone areas. The primary conditions monitored are air pressure, snow density, snow depth, snow temperature, wind velocity, wind direction, and ambient air temperature. All critical aspects of the telemetering system have been specified, including the sensors, transmitter/receiver, and telemetry frame design. Aspects of the system packaging and the link budget which are unique to the alpine environment are discussed.
