Abstract

This letter derives a turbo multiuser detector with linear minimum mean squared error (MMSE) filtering using a-priori information in order to reduce the computational complexity. The equivalence of the turbo multiuser detector developed in this letter and the one based on soft interference cancellation followed by a linear MMSE filtering is established.
