Abstract

Abstract

In this paper, a time delay estimate algorithm based on analysis of cross-correlation sequence of model error and input signal is proposed, and a method to build behavioral model of power amplifiers dynamically depend on the new delay estimate algorithm is discussed. Using this method, a non-union delay Memory Polynomial(MP) model is built. Simulation results show the new algorithm can find main delays in output signal effectively and reduce the delay length of traditional MP model from 6 to 2 at the cost of 3 dB increase of models NMSE, which means the algorithm can achieve a good balance between model complexity and its precision.
