A study on a high-speed Gaussian random number generator

Abstract

Gaussian random number generators are employed to simulate the fading phenomena and additive white Gaussian noise of the radio channel. High speed Gaussian random number generators are most important components for the real-time channel simulation of the CDMA systems, because of channel's wideband nature. In this paper we suggest a Gaussian random number generation method, based on central limit theorem with the simple probability density conversion before addition. Using this technique, we can omit some of the input random numbers and adders, which are relatively complex components in the hardware logic of the random number generator.
