Pilot Design for MIMO-OFDM with Beamforming

2007
Reference symbols (pilots) support coherent detection, but add overhead and consume transmit power. A sophisticated pilot design needs to trade-off the attainable channel estimation accuracy with the induced losses in bandwidth & power efficiency. MIMO transmission, transmit beamforming, and spatial multiplexing further complicate pilot design. In this

An electronic navigational aid for pilots-designed by pilots

Oceans '97. MTS/IEEE Conference Proceedings, 1997
Summary form only given, substantially as follows. There have been significant advances in wireless communications as well as increased utilization of the Global Positioning System (GPS) for commercial navigation systems. A major component in maritime applications of these technologies is a portable shipboard system that provides more that own-ship ...

An uplink pilot design for IEEE802.16m

2011 IEEE 3rd International Conference on Communication Software and Networks, 2011
This paper provides some design considerations of pilot structure for 1-antenna and 2-antenna IEEE802.16m. Space-Zone (SP-Zone) and Mobility-Zone (MB-Zone) concepts are introduced to use different numbers of subcarriers and symbols between pilots according to the radio environment and mobile speed to improve the system performance comparing with the ...
