Abstract
The performance of communication systems should be tested against a set of requirements. To this end, noise generation systems are used to generate noise signals with specified characteristics. In this paper, we propose the area & power-efficient noise generation system based on DCT method. It is shown that the proposed structure results in area reduction of non-DCT block by 44∼47%. Moreover, since the proposed structure does not use high-speed internal clock, it achieves power reduction by 74∼77%.
