| Abstract: |
| In the new generation wireless communication systems,iterative detection is widely studied and used due to good detection performance.This paper studies the interleaving and iterative detection algorithm,and uses it in the multi-hop relay system.Adopted with OFDM and MIMO technology,the performance of multi-hop relay system is evaluated.Also,a two time slot transmission scheme is proposed for IDMA-MIMO-OFDM systems,which can overcome the self-interference during the multi-hop transmission,achieve a high spatial diversity gain,and obtain a flexible system architecture and more powerful transmission ability. |
