Convex Approximation Algorithms for Back-Pressure Power Control
(2012)Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint ... -
Distributed back-pressure power control for wireless multi-hop networks
(2012)A key problem in wireless networking is how to choose a link activation schedule and associated powers in concert with routing decisions to optimize throughput. Back-pressure control policies are optimal in this context, ... -
Dynamic resource allocation in CDMA systems with deterministic codes and multirate provisioning
(2006)Next generation wireless CDMA systems will provide high and variable data rates by using multicode structures, controllable code spreading gains, and transmit power adaptation. We address the emerging resource allocation ... -
The impact of space division multiplexing on resource allocation: A unified treatment of TDMA,OFDMA and CDMA
(2008)Space division multiple access (SDMA) with an antenna array at the transmitter is a promising means for increasing system capacity and supporting rate-demanding services. However, the presence of an antenna array at the ...
