4G Wireless Communication Systems

With the advent of the next generation (4G) broadband wireless communications, the combination of MIMO (Multiple-Input Multiple-Output) wireless technology with Multi-Carrier CDMA (MC-CDMA) has been recognized as one of the most promising techniques to support high data rate and high performance. Moreover, future mobile devices will have to propose interoperability between wireless communication standards (4G, WiMax ...) and then implement MIMO pre-coding, already used by WiMax standard. Finally, in order to maximize mobile devices lifetime and guarantee quality of services to consumers, 4G systems will certainly use cooperative MIMO schemes or MIMO relays. Our research activity focuses on MIMO pre-coding and MIMO cooperative communications with the aim of algorithmic optimization and implementation prototyping.
