Title:	DEPENDENCY BETWEEN ERROR VARIANCE OF THE A PRIORI INFORMATION AND A MODIFIED CHANNEL NOISE VARIANCE IN TURBO-EQUALISATION
Authors:	Gilles Gorlier, Sylvie Perreau, University of South Australia, Australia; Inbar Fijalkow, ENSEA - University of Cergy-Pontoise - CNRS, France
Abstract:	In this paper, we propose a method based on the modification of the channel noise variance at the equaliser input in order to improve the performance of a turbo-equaliser. We will show a relation between the modified channel noise variance and the a priori information statisitcs. The simulation are done for 2 types of turbo-equalisers.
