— Three strategies for improving the performance of point-to-point Bluetooth links are presented. All of the strategies are implemented on the host computer, and therefore no modification of the Bluetooth standard is necessary. The first strategy is custom error control coding, which is achieved by transporting BCH code words within AUX1 packets. The second(More)
— In this paper, radiation from microwave ovens is measured using PRISM, a custom-built device designed to measure transmissions in the ISM band. The measured signals, treated as a rising noise floor, are then applied to a semi-analytic simulation to determine the probability of frame error rate (FER) per channel for six Bluetooth packet types [1]. I.(More)
The Software-Defined Radio (SDR) research community currently needs an implementation of the SCA core framework (CF) that is open to modifications, free, simple, and in C++. Recognizing this need Virginia Tech has developed and released OSSIE (Open Source SCA Implementation::Embedded). This paper describes the underlying philosophy for the development of(More)
The design and implementation of the Virginia Tech Space-Time Advanced Radio (VT-STAR), a multiple antenna element space-time (ST) processing prototype testbed, is presented. The testbed is a research tool for comparing practical and theoretical performance metrics (e.g., throughput, link reliability) in different wireless channel conditions. The prototype(More)
