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...

Universal Languages and the Power of Diagonalization
We define and study strong diagonalization and compare it to weak diagonalization, implicit in [7]. Kozen’s result in [7] shows that virtually every separation can be recast as...
