Abstract--There has been a great deal of attention on cooperative communication which exploits the spatial diversity among antennas belonging to multiple terminals. Most of the exi...
The closed-loop transmit diversity technique is used to improve the performance of the downlink channel in MIMO communication systems. In these closed-loop systems, feedback delay...
— A multi-hop virtual cellular network (VCN) was proposed for future mobile communication systems. In VCN, the transmitted signal from a mobile terminal is relayed via multi-hop ...
