Time Related Factors of Data Accuracy, Completeness, and Currency in Multi-Channel Information Systems
Multi-channel information systems involve data redundancy, which, in turn, requires the implementation of synchronization mechanisms among overlapping databases. This need for peri...

Performance of Multi-User MIMO Precoding with Limited Feedback over Measured Channels
Abstract—In multi-user multiple-input multiple-output (MUMIMO) systems, channel state information at the transmitter (CSIT) allows for multi-user spatial multiplexing and thus in...

Dynamic Power Allocation Under Arbitrary Varying Channels - The Multi-User Case
Abstract—We consider the power control problem in a timeslotted wireless channel, shared by a finite number of mobiles that transmit to a common base station. The channel betwee...

Opportunistic power allocation for fading channels with non-cooperative users and random access
— We present a game-theoretical model of a wireless communication system with multiple competing users sharing a multiaccess fading channel. With a specified capture rule and a ...

Delay Analysis for Cognitive Radio Networks with Random Access: A Fluid Queue View
Abstract—We consider a cognitive radio network where multiple secondary users (SUs) contend for spectrum usage, using random access, over available primary user (PU) channels. Ou...
