In this paper a exible, high-throughput, low-complexity additive white gaussian noise (AWGN) channel generator is presented. The proposed generator employs a Mersenne-Twister to generate a long random number uniformly distributed sequence and a Box-Muller transformation implementation to derive gaussian noise samples. Emphasis is given on developing a high-throughput approximation unit for the elementary functions required for the transformation. The proposed techniques are shown to lead to
