Title: A new algorithm to blind separate QAM signals in narrowband MIMO communication systems
Abstract: In this paper we present a new algorithm to blind separate QAM signals in narrowband MIMO (MultipleInput Multiple-Output) communication system. It is based on the infinite norm and named CQA (Constant sQuare Algorithm). The analysis of the stationary points of the proposed cost function shows that the only existing minima correspond to perfect separation of source signals. The simulation results show that our new algorithm has better performances compared to CMA (Constant Modulus Algorithm) with comparable complexity.
