Abstract
Noise generation systems are used to generate noise signals with specified characteristics. In recent study, DCT-based noise generation system outperforms the conventional noise generation system when a noise model requires complicated PSD(Power Spectral Density) specifications. In this paper, we propose the area-efficient noise generation system based on DCT method. It is shown that the proposed system results in area reduction by 61~64% except DCT block. Furthermore, it achieves power reduction by 41~56%.
