Abstract :
The gradient algorithm of TR is subject to aberration about frequency domain signal, and this kind of aberration is cumulative with the increase of iterations, so the aberration can not be neglected for the signal. This paper adopts an improved gradient algorithm which realize the iteration with some certain searching space, and then it can reduce the aberration as possible, also make sure the better peak clipping performance.
