Abstract :
Low-complexity multi-user MIMO detector of QAM signals based on long scrambling codes is proposed for HSUPA to improve its capacity and handle the near-far problem. Furthermore, additional block-interleaving connecting spreading and scrambling is designed in the physical layer of HSUPA for better orthogonality between users. Simulations show the efficiency of this enhancement, which ensures it a promising technique for HSUPA
