This paper explores the problem of non-coherent multiuser weight/phase optimal joint detection for QPSK signal in over-saturated multiple access communication. Firstly, non-coherent multiuser weight/phase estimator is given via theoretical analysis. Then, the low complexity non-coherent multiuser weight/phase optimal joint detection algorithm is proposed, which is fit with practical working-condition and is applicable to linear modulation methods with two-dimensional constellation. Finally, the performance of the non-coherent optimal receiver and the phase estimate error is analyzed via computer simulation and some useful conclusions are drawn.
