On the Optimal Number of Active Receivers in Fading Broadcast Channels
Abstract--For broadcast channels, a power allocation scheme is proposed to maximize the number of active receivers, for each of which, a minimum rate Rmin > 0 can be achieved. U...

Jamming in Fixed-Rate Wireless Systems with Power Constraints - Part I: Fast Fading Channels
This is the first part of a two-part paper that studies the problem of jamming in a fixed-rate transmission system with fading, under the general assumption that the jammer has no...

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...

A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...

Fair resource allocation under Rayleigh and/or Rician fading environments
—Proportional fair scheduling (PFS) provides good balance between throughput and fairness via multi-user diversity and game-theoretic equilibrium. Very little analytical work exi...
