Abstract— Consider the problem of base-station and subcarrier assignment on the downlink of a two-cell OFDMA system with adaptive modulation. The aim is to maximize a common data...
The Open Spectrum approach to spectrum access can achieve near-optimal utilization by allowing devices to sense and utilize available spectrum opportunistically. However, a naive d...
File-sharing applications remain today the most representative and popular realization of the Peerto-Peer paradigm. Large objects receive an increasing amount of interest in such s...
—In 3G data networks, network operators would like to balance system throughput while serving users in a fair manner. This is achieved using the notion of proportional fairness. ...
—This paper exploits the use of location information of wireless terminals to improve the performance of a beamforming system and support multiple access. Based on a system provi...
