摘要：
In this paper, we consider a blind separation problem for single-channel mixtures of two QPSK signals, which have the same symbol rates. However, the present method is short of efficiency. To this question, we present a periodic linear multi-in multi-out model which is constructed by over-sampling. Under this condition, an algorithm based on lattice reduction (LR) and decision feedback equalization (DFE) is proposed for symbol detection. Simulation results are provided to illustrate the performance of the proposed algorithm.
