New method for improving convergence procedure of incremental multiparameter algorithm

Real-time implementation of high resolution algorithms is difficult, especially in coherent environment. This paper proposes a new method to speed up its convergence procedure. For the same 3-source case, the results of 100 simulation trials indicate that arbitrary assignment of initial estimates does not affect convergence. These 100 trials indicate that original IMP needs most probably 20 iterations and this modified IMP algorithm requires most probably only 14 iterations. For a 4-source case, our work shows a saving of about 40%. As the number of sources increases, a further increase in saving of iterations percentage-wise may be expected.
