Abstract :
The performance of communication systems should be tested against a set of requirements. This procedure requires various noise sources to be connected onto the line to inject the specified noise signals into the receiver of the communication system. In this paper, a flexible noise generation algorithm using DCT is proposed. It is shown that the proposed method outperforms conventional methods when a noise model requires complicated PSD specifications
