Abstract

A signal processing procedure for distributed resource allocation (power and rate management) in telecommunication systems is here introduced. A generalized approach towards adaptive modulation is discussed, as a noncooperative joint modulation, rate and power control game for the uplink of a single cell CDMA system. Then, an iterative algorithm to select the best power and rate values for the desired modulation is presented. Performance analysis is finally carried out in comparison with conventional joint rate and power control approach, also based on game theory.
