random noise

random noise

[′ran·dəm ′nȯiz]
(mathematics)
A form of random stochastic process arising in control theory.
(physics)
Noise characterized by a large number of overlapping transient disturbances occurring at random, such as thermal noise and shot noise. Also known as fluctuation noise.

random noise

A type of noise comprised of transient disturbances which occur at random times; its instantaneous magnitudes are specified only by probability distribution functions which give the fraction of the total time that the magnitude lies within a specified range.

Government officials said that once the country gets the "Pseudo Random Noise" code it will start the process of inputting it into KASS.
The average number of subcarrier samples will be larger when the tap size increases, which is more conducive to suppress random noise. However, if the number is too large, the correlation between the subcarrier samples may be weakened, so the accuracy of channel estimation may be affected.
