Power and Rate Allocation in Multicell Multiuser OFDM

Abstract:

Multicell Multiuser Orthogonal Frequency Division Multiplexing (MM-OFDM) is a promising technique for achieving high-speed transmission in cellular wireless communication systems. In this thesis, we consider resource allocation over the downlink of multiple transmitters. It aims at maximizing the weighted sum rate of users subject to their independent fixed or minimum rate constraints, while the transmission power of each transmitter is limit. By using the Karush-Kuhn-Tucker (KKT) conditions, the dual optimum can be achieved with relatively high complexity. It will be used as the reference to evaluate the heuristic methods designed in future. In this talk, first, the considered scenario will be introduced. Then, the present results will be shown. At last, the prospect of future work will be given.
