Journal ArticleDOI
Two signaling schemes for improving the error performance of frequency division duplex (FDD) transmission systems using transmitter antenna diversity
TL;DR: Two signaling schemes that exploit the availability of multiple (N) antennas at the transmitter to provide diversity benefit to the receiver are proposed and can suppress co-channel interference.
Patent
Multi-mode controller
Jeyhan Karaoguz,Nambi Seshadri +1 more
TL;DR: In this article, a portable communication device constructed according to the invention can communicate with different networks as the device is moved through the areas of coverage supported by the different networks, as a result, the device can take advantage of services provided by a particular network when it is within the area of coverage provided by that network.
Patent
Proximity authentication system
TL;DR: In this paper, a user's credentials are stored on an RFID token, and an R-ID reader is implemented within a security boundary on the computing device, so that the credential can be passed to the security boundary without passing through the computing devices via software messages or applications.
Journal ArticleDOI
Subband speech coding and matched convolutional channel coding for mobile radio channels
TL;DR: It is shown that there is a difference in error sensitivity of four orders of magnitude between the most and the least sensitive bits of the speech coder, and a family of rate-compatible punctured convolutional codes with flexible unequal error protection capabilities have been matched to thespeech coder.
Patent
Method of creating incentives for establishing hotspot locations
Jeyhan Karaoguz,Nambi Seshadri +1 more
TL;DR: In this paper, an access point is provided to a wireless hotspot for wireless devices to wirelessly connect to a larger network in a publicly accessible location, and use statistics are evaluated of the access point of the hotspot by portables devices.
