In this paper, we consider separation and decoding for two QPSK signals, which have the same symbol rates. However, the complexity of the present method is too high. To solve this question, an algorithm based on lattice reduction and joint iteration is proposed to enhance the separation performance. The complexity is greatly reduced while retains considerable performance. Simulation results are provided to illustrate the performance of the proposed algorithm.
