Abstract :
Hardware emulation of communication channels can speed up the process of estimating the performance of a communication system by a few orders of magnitude compared with traditional software-based estimations. This paper proposes a novel method for efficient implementation of additive white Gaussian noise (AWGN) generators in FPGAs for channel emulators. Compared to existing methods, the proposed method is faster and simpler to adopt. In this paper, the architecture and the performance analysis of our AWGN generators are elaborated.
