Abstract
- In this paper, distributed joint power and frequency allocation problem is studied. First, we present a distributed power update algorithm for the general wireless networks that eliminates the feasibility issue encountered in the well-known Foschini-Miljanic algorithm. Then, the proposed algorithm is extended by considering Orthogonal Frequency Division Multiple Access (OFDMA) femtocell networks in which each femto base station has more than one user. In addition, a frequency allocation scheme is developed in order to increase the maximum achievable signal-to-interference-plus-noise ratio (SINR). Subsequently, we present a joint frequency/power update algorithm by combining the proposed frequency allocation scheme with the power update algorithm. Convergence and optimality analyses of all the proposed algorithms are carried out and the theoretical results are illustrated with numerical results. [ABSTRACT FROM AUTHOR]
