A mapping algorithm of superposed signals in two-way relaying system
2014
Two-way relaying systems have shown its advantage in enhancing the capacity performance in literature. However, there are many difficulties in the practical implementation. In this paper, an effective mapping algorithm of superposed signals is proposed based on the Binary Phase Shift Keying (BPSK) modulation. It is rather more suitable for implementation than the existing scheme derived from the Minimum Euclidean distance criterion, since it has the equal performance with the existing method proved by the simulation results, but much lower computational complexity.
