Abstract
The aim of this paper is to design the loop coefficients in real time in order to obtain a good trade-off in terms of performance with respect to both noise and to dynamics. In this work the optimization is performed while considering an input signal whose frequency assumes a generic shape. A cost function is built which takes into account in the same time both the transient and the steady state error due to the dynamics besides the noise contribution. Some simplifications allow a realtime computation, so that the algorithm can be implemented in a real-time fully software receiver.
