A Virtual Layered Space Time Receiver With Maximum Likelihood Channel Detection
This paper proposes a novel receiver architecture named as "Virtual layered space time reception" for MIMO wireless communication systems. In the proposed reception architecture, a transmission signal is regarded to comprise a sign signal and fractional phase shift. The phase shift combined with wireless channels are dealt as a virtual channel. Then, the sign signal which is assumed to be transmitted over the virtual channel is detected by a Serial Interference Canceler (SIC) like V-BLAST. The receiver based on the proposed architecture can detect more data streams than the number of received antennas, even though the architecture applies the SIC.
