Multiantenna Cellular Communications: Channel Estimation, Feedback, and Resource Allocation (2011)
Abstract / truncated to 115 words
The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.g., video streaming). The potential gain of employing multiple antennas for downlink transmission is well recognized: the total data throughput increases linearly with the number of transmit antennas if the spatial dimension is exploited for simultaneous transmission to multiple users. In the design of practical cellular systems, the actual benefit ... toggle 5 keywordschannel estimation – limited feedback – MIMO – multicell communications – resource allocation
