In this paper, we consider
power control
for the uplink of a directsequence codedivision multipleaccess data network. In the uplink, the purpose of
power control
is for each user to transmit enough power so that it can achieve the required
quality of service
without causing unnecessary interference to other users in the system. One method that has been very successful in solving this purpose for
power control
is the gametheoretic approach. The problem for
power control
is modified as a
Nash equilibrium
problem in which each user can choose its transmit power in order to maximize its own utility, and a
Nash equilibrium
is an ideal solution of the powercontrol game. We present a noncooperative powercontrol game in which each user can choose the transmit power in a way that it gets the sufficient signaltointerferenceplusnoise ratio and maximizes its own utility. To ensure the existence of a solution, we also propose the
variational inequality problem
which is connected with the proposed game. On a linear receiver, we deal with the
matched filter
receiver. Next we present a new ergodic algorithm for the proposed
power control
because the existing iterative algorithms can not be applied effectively to the proposed power control. We also present
convergence analysis
for the proposed algorithm. In addition, applying the proposed algorithm to the proposed power control, we provide numerical examples for the transmit power, the signaltointerferenceplusnoise ratio and so on. Numerical results for the proposed algorithm shall show that as compared with the existing powercontrol game and its method, all users in the network can enjoy the sufficient signaltointerferenceplusnoise ratio and achieve the required quality of service.
