文摘
A novel complex-valued orthogonal least squares algorithm is developed.
The algorithm truncates Volterra series and estimates the kernel at one time.
The algorithm can also indicate the divergence of Volterra series.
Comparing the simulation results with the analytical ones validates the algorithm.
