Reading List Version 1.0 This Conference brings together academics, policymakers, spectrum users, and advocates to examine the extent of, and trends in, radio noise pollution and to suggest how the associated policies and regulations might need to be adjusted to reflect changes in radio noise levels. This Reading List offers participants background reading and references, organized in reverse c...

One of the parameters driving the performance of the Wide Area Augmentation System (WAAS) is the Grid Ionospheric Vertical Error (GIVE). The GIVE bounds the estimation error of the ionospheric delay at each Ionospheric Grid Point (IGP). The GIVE is generated such that a user interpolating both the vertical ionospheric delays at the IGP and the GIVE, is protected. The GIVE is a function of sever...

The first step, before investigating physical origins of noise in resonators, is to investigate correlations between external measurement parameters and the resonator noise. Tests and measurements are mainly performed on an advanced phase noise measurement system, recently set up. The resonator noise is examined as a function of the sensitivity to the drive level, the temperature operating poin...

Phase noise is a property of an oscillator that can extend in magnitude from the carrier of several volts down to a mere nano-volt far from the carrier. In many cases the lowest noise OCXOs, SAWs and other specialty oscillators have carrier to noise ratios in excess of -180 dBc/√Hz. The noise level of these oscillators often extends below that of even the mixers and low noise amplifiers at base...

researchers suggested that the individual fit test be conducted to estimate the protection effectiveness of workers’ hearing protection device (hpd) while working. practically, it is convenient to conduct single, instead of multiple, fit test measurement. this study examined if a single trial of earplug fit test can represent multiple performances. additionally, it investigated how much noise e...

This paper proposes a new method fo r noise parameter measurement of microwave devices. Instead of measuring the noise figure, the optimum source impedance r o p t is determined by measuring the noise powers corresponding to cold impedances, then the minimum noise figure Fmn ( 0 r minimum effective noise temperature T,,,) and noise conductance Gn are determined by connecting a calibrated hot no...

Data association target tracking algorithms assume knowledge of target detection probability and sensor measurement noise. They are unknown and/or variable. Target signal is unknown due to unknown and time-varying target radar cross section as well as multi-path signal attenuation and variable propagation signal losses. Noise power is unknown due to the presence of unknown clutter signal whose ...
