On the Complexity of Decoding Lattices Using the Korkin-Zolotarev Reduced Basis
—Upper and lower bounds are derived for the decoding complexity of a general lattice L. The bounds are in terms of the dimension n and the coding gain of L, and are obtained ba...

A cooperative uplink power control scheme for elastic data services in wireless CDMA systems
We consider the uplink power control problem in a single cell CDMA wireless data system. Each user specifies upper and lower QoS bounds. We formulate the considered problem as a g...

Brief announcement: collaborative measurement of upload speeds in P2P systems
We define and study the bandwidth determination problem in adhoc P2P environments. Using point-to-point bandwidth probes, the goal is to quickly determine each host's upload ...
