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...

OFDMA Downlink Resource Allocation for Ergodic Capacity Maximization with Imperfect Channel Knowledge
In this paper, we derive an optimal resource allocation algorithm for ergodic weighted-sum capacity maximization in OFDMA systems assuming the availability of only partial (imperfe...

Joint channel estimation and resource allocation for MIMO systems-part I: single-user analysis
Multiple antenna systems are known to provide very large data rates, when the perfect channel state information (CSI) is available at the receiver. However, this requires the recei...

Resource allocation for OFDMA cognitive radios under channel uncertainty
A weighted sum-rate maximization problem is considered for an access point (AP) allocating resources to wireless cognitive radios (CRs) communicating using orthogonal frequency-di...

Orthogonal STBC in General Nakagami-m Fading Channels: BER Analysis and Optimal Power Allocation
Abstract— We analyze the performance of multiple-input multiple-output (MIMO) systems employing orthogonal space-time block codes (STBC) in general Nakagami-m fading channels wit...
