Ultra-wideband — (aka UWB, ultra wide band, ultraband, etc.) is a radio technology that can be used at very low energy levels for short range high bandwidth communications by using a large portion of the radio spectrum. UWB has traditional applications in non… … Wikipedia
Additive white Gaussian noise — Explanation= In communications, the additive white Gaussian noise (AWGN) channel model is one in which the only impairment is the linear addition of wideband or white noise with a constant spectral density (expressed as watts per hertz of… … Wikipedia
Low-noise block converter — A low noise block converter (LNB, for low noise block, or sometimes LNC, for low noise converter) is the (receiving, or downlink) antenna of what is commonly called the parabolic (actually paraboloid) satellite dish commonly used for satellite TV … Wikipedia
