Abstract :
In this paper we apply a modification scheme of the parallel interference cancellation (PIC), recently proposed by Tanaka and Okada based on techniques of the statistical neurodynamics, to the linear PIC (LPIC) with a tentative soft decision function f(x)=ax, and show that the modification enhances its convergence property.
