Space-time interference rejection cancellation in transmit diversity systems
2002 (English)In: 5TH INTERNATIONAL SYMPOSIUM ON WIRELESS PERSONAL MULTIMEDIA COMMUNICATIONS, VOLS 1-3, PROCEEDINGS, NEW YORK: IEEE , 2002, 706-710 p.Conference paper (Refereed)
In this paper, we consider the use of space diversity methods in conjunction with interference rejection combining (IRC) to mitigate the impact of interference and noise for interference limited scenarios. The use of transmit diversity schemes in a system, will in general limit the interference rejection capabilities of IRC techniques. We introduce a novel space-time IRC (STIRC) scheme that exploits the spatio-temporal correlation induced by cochannel users employing transmit diversity in the form of space-time block codes (STBC). Thus, the system can draw, upon the benefits of interference rejection methods although transmit diversity is being employed. Simulation examples are presented to illustrate the discussion and to highlight the importance of taking both the spatial and temporal structure of the interference into account.
