Capacity analysis of a PMR system with DAB downlink
(IEEE, 2003)Several trunked private mobile radio (PMR) systems have been designed over the last decade, most of which have symmetric downlink and uplink channel capacities. These systems may not be spectrally efficient in case of group ... -
Computer aided frequency planning for the radio and TV broadcasts
(Institute of Electrical and Electronics Engineers, 1996-06)The frequency planning of the VHF and UHF broadcasts in Turkey is described. This planning is done with the aid of computer databases and digital terrain map. The frequency offset is applied whenever applicable to increase ... -
Metamaterial-based wireless strain sensors
(American Institute of Physics, 2009-07-07)We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain ... -
Threshold broadcast encryption with reduced complexity
(IEEE, 2007-11)Threshold Broadcast Encryption (TBE) is a promising extension of threshold cryptography with its advantages over traditional threshold cryptosystems, such as eliminating the need of a trusted party, the ability of setting ...
