Abstract
Noise generation systems are used to generate noise signals with specified characteristics. In recent study, noise generation system using DCT outperforms the conventional noise generation system when a noise model requires complicated PSD (Power Spectral Density) specifications. In this paper, high density and low power structures of non-DCT block in DCT-based noise generation system are proposed. Simulation results show that the high density structure results in area reduction by 61 ~ 64% and the low power structure achieves power reduction by 88 ~ 89%.
