Sensitivity (radio receiver) — A receiver s sensitivity is a measure of its ability to discern low level signals.Sensitivity in a receiver is normally taken as the minimum input signal (Smin) required to produce a specified output signal having a specified signal to noise… … Wikipedia
MIMO — This article is about MIMO in wireless communication. For other uses, see MIMO (disambiguation). Understanding of SISO, SIMO, MISO and MIMO (note that the terms input and output refer to the radio channel carrying the signal, not to the devices… … Wikipedia
Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… … Wikipedia
Preamplifier — Preamp redirects here. For the device used in professional audio, see Microphone preamplifier. An example of a typical high end stereo preamplifier. A preamplifier (preamp) is an electronic amplifier that prepares a small electrical signal for… … Wikipedia
Noise (radio) — In radio reception, noise is the superposition of white noise (also called static ) and other disturbing influences on the signal, caused either by thermal noise and other electronic noise from receiver input circuits or by interference from… … Wikipedia
Noise temperature — In electronics, noise temperature is one way of expressing the level of available noise power introduced by a component or source. The power spectral density of the noise is expressed in terms of the temperature (in kelvins) that would produce… … Wikipedia
Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… … Wikipedia
Noise figure — (NF) is a measure of degradation of the signal to noise ratio (SNR), caused by components in a radio frequency (RF) signal chain. The noise figure is defined as the ratio of the output noise power of a device to the portion thereof attributable… … Wikipedia
Precoding — is generalized beamforming to support multi layer transmission in MIMO radio systems. Conventional beamforming considers linear single layer precoding so that the same signal is emitted from each of the transmit antennas with appropriate… … Wikipedia
Matched filter — In telecommunications, a matched filter (originally known as a North filter[1]) is obtained by correlating a known signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to… … Wikipedia
Radar — For other uses, see Radar (disambiguation). A long range radar antenna, known as ALTAIR, used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll … Wikipedia
