Abstract :
A modified MMSE multiuser detection structure is proposed, which jointly elaborate the received signal and its complex conjugate. Simulation results show that the new structures significantly outperform the conventional MMSE structure, in terms of suppression capability of both multiple-access interference and narrowband interference.
