Abstract
Abstract—The authors consider a multirate code-division mul-tiple acess system, in which all users have the same chip rate and vary their data rate by adjusting the processing gain. The receivers are assumed to be implemented using conventional matched filters, whose performance is sensitive to the received power levels. The au-thors ’ goal is to maximize the total system throughput by means of power control. A game theoretic approach is adopted. It is shown that for a certain type of pricing function, a unique Nash equilib-rium solution exists and it possesses nice global properties. For ex-ample, it can be shown that for the optimal solution a high-rate connection should maintain a higher energy per bit than low-rate ones. The asymptotic spectral efficiency is also derived. Index Terms—Multirate CDMA systems, Nash equilibrium, noncooperative game, power control. I.
