Blind detection of co-channel signals in wireless scenarios may be achieved with the help of data precoding techniques. In this letter we propose a new data precoding / blind detection approach that is based on a unique modification to the signal constellation of each of the co-channel signals. Detection is based on exploiting the embedded constellation property. The new approach can be seen as a generalization to some earlier precoding techniques that were based on phase modifications. Demonstration of the proposed method involves application to 8-ary amplitude-phase modulations, with performance shown to be reasonably close to an MMSE receiver. Performance results for a semi-blind receiver for 4-ary signaling are also given to demonstrate further possible applications of the new scheme.
