In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks supporting simultaneously both real-time and non-real-time services with various and often diverse Quality of Service (QoS) prerequisites. Each mobile is associated with a nested QoS-aware utility function that characterizes its degree of satisfaction(More)
In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks, emphasizing on the support of real-time services' QoS prerequisites. The corresponding problem is formulated as a non-cooperative game where users aim selfishly at maximizing their utility-based performance under the imposed physical limitations. A(More)
SC-FDMA has been selected by the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) and LTE Advanced (LTE-A), as the primary multiple access scheme for the uplink of the 4 G wireless communication systems. This article surveys the different state-of-the-art resource allocation algorithms developed to allocate system's subcarriers and(More)
