A distributed, energy-efficient power control algorithm for the uplink of a CDMA wireless data network over a frequency-selective and slow-fading channel is derived through the application of noncooperative game theory, focusing on the issue of initial code synchronization. To capture the tradeoff between obtaining good synchronization performance and saving as much energy as possible, we derive a distributed criterion to properly set the receiver decision threshold and the transmit power, using the generalized Nash solution, and we propose a practical algorithm, based on iterative best-response dynamics. © 2011 IEEE.

Abstract
A distributed, energy-efficient power control algorithm for the uplink of a CDMA wireless data network over a frequency-selective and slow-fading channel is derived through the application of noncooperative game theory, focusing on the issue of initial code synchronization. To capture the tradeoff between obtaining good synchronization performance and saving as much energy as possible, we derive a distributed criterion to properly set the receiver decision threshold and the transmit power, using the generalized Nash solution, and we propose a practical algorithm, based on iterative best-response dynamics. © 2011 IEEE.File in questo prodotto:
