Abstract :
Summary form only given. This talk is a review on our ongoing research effort to design multi-user Multiple Input Multiple Output (MIMO) systems based on chip-level space-time coded CDMA system. It is characterized by its innovative spreading and space-time codes, namely three dimensional complementary codes (3DCCs), which offer a unique paradigm to design space-time coded signature codes for multi-user MIMO systems. The proposed system achieves interference-resistant performance owing to the unique correlation properties of 3DCCs. It has an ability to offer diversity and multiplexing advantages at the same time with a flexible tradeoff between diversity and multiplexing gains to suit for varying channel conditions and application requirements. Additionally, its multi-dimensional sequence design provides an extra frequency diversity gain for its further performance improvement.
