The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

The analytical constant modulus algorithm (ACMA) is an algebraic method for blind separation of co-channel users. Assuming constant modulus (CM) sources, we propose the linearly precoded ACMA (LPACMA) for blind separation of systems employing space-time codes (STCs) that do not preserve the CM property (non-CM STCs). The proposed algorithm requires fewer snapshots than STC-ACMA and resolves the permutation ambiguity inherent to blind algorithms whilst retaining the asymptotic convergence to the Wiener receiver. © 2005 Elsevier GmbH.
