Abstract

Abstract

In this paper, a semi-blind closed-form co-channel signal separation method is proposed, which is based on two steps. The first is to estimate the zero space of multi-users signals. The second is to estimate them using LMS method and some short sequence, which is always known in digital communication system. Compared with non-blind ones, the new method needs very short sequence, the shortest length of which is equal to the number of co-channel users. At the same time it can overcome the shortcoming of blind ones in computational complexity and lack of global convergence. The computer simulation demonstrates that the. new method is suitable for co-channel signal separation in smart antenna systcin when mult,ipath exists.
