Description
Summary:This paper presents a method for designing a high-accuracy white Gaussian noise generator suitable for communication channel emulation. The proposed solution is based on the combined use of the Box-Muller method and the central limit theorem. The resulting architecture provides a high-accuracy AWGN with a low-complexity architecture for digital implementation in FPGA. The performance is studied by means of MATLAB simulations, and various complexity figures are given. (Author)
