— 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)
— 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)
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)
We study in this paper uplink scheduling for V-BLAST users. Each user spatially multiplexes his data over multiple transmit antennas. This spatial multiplexing (SM) scheme provides high data rates while multi-user diversity obtained from scheduling improves the performance of the uplink system. The scheduler selects one user at a time based on a criterion(More)
