Abstract :
In this paper we present a new blind signal separation algorithm for data symbols belonging to a real constellation, e.g. BPSK. The algorithm is based on a direct estimation of the transmitted symbol sequences without identifying the mixing matrix. We show that for a real constellation, a simple linear coding scheme allows for a non-iterative separation. The coding scheme maintains the information rate without increasing the bandwidth
