Channel gain equal square root of power
 - Wikipedia)
Signal-to-noise ratio (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. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal … See more Signal-to-noise ratio is defined as the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): where P is average … See more All real measurements are disturbed by noise. This includes electronic noise, but can also include external events that affect the measured phenomenon — wind, vibrations, the … See more When a measurement is digitized, the number of bits used to represent the measurement determines the maximum possible signal-to … See more Signal to noise ratio may be abbreviated as SNR and less commonly as S/N. PSNR stands for peak signal-to-noise ratio. GSNR stands for … See more An alternative definition of SNR is as the reciprocal of the coefficient of variation, i.e., the ratio of mean to standard deviation of a signal or … See more Amplitude modulation Channel signal-to-noise ratio is given by $${\displaystyle \mathrm {(SNR)_{C,AM}} ={\frac {A_{C}^{2}(1+k_{a}^{2}P)}{2WN_{0}}}}$$ where W is the bandwidth and Output signal-to … See more Optical signals have a carrier frequency (about 200 THz and more) that is much higher than the modulation frequency.

[3] The term root-power quantity refers to the square root that relates these quantities to power. The term was introduced in ISO 80000-1 § Annex C ...
WebNon-ergodic channel ; The channel gain is a random variable and does not change with time. The channel gain process is stationary but not ergodic, i.e., the time average is not equal to the ensemble average. In other words, the randomness of the channel gain can not be averaged out (removed) over time.
WebThe amplification is the square root of the size of the FFT. The size of the FFT can be determined from the sampling rate of the time domain waveform (info.SamplingRate) and the subcarrier spacing (15 kHz).
