Abstract:

Aiming at the problems of computer precision and even overflow, a new modified algorithm is proposed. The complex-time distribution algorithm can be accomplished effectively by frequency spectrum iteration estimation and signal scale conversion. Simulation results show that the proposed method has a good ability to suppress the influence of noise interferences, improve the energy convergence, and provide theoretical and technical support for the enginnering application.

Key words: complex-time distribution, complex-lag signal, time frequency energy concentration
