Distributed Resource Allocation for Downlink Multicell OFDMA Systems
This paper addresses resource allocation for sum throughput maximization in a sectorized two-cell downlink OFDMA systems impaired by multicell interference. It is well known that the optimization problem for this scenario is NPhard and combinational, which is here converted to a novel sum throughput maximization problem based on the intercell interference limitation. Then, two subclasses of thi...
متن کاملDownlink Radio Resource Allocation Scheme for Ofdma Cellular Network
This paper presents radio resource allocation scheme to maximize ergodic rates for OFDMA cellular network .Purpose behind this is to improve multiuser diversity. Objective of this paper is to improve multiuser diversity along with maximum ergodic rates.SNR is considered to maximize erotic rates, along with that packet size is also considered. In this paper an algorithm is proposed in which crit...
متن کاملResource Allocation for Downlink Cellular OFDMA Systems: Part I - Optimal Allocation
In this pair of papers (Part I and Part II in this issue), we investigate the issue of power control and subcarrier assignment in a sectorized two-cell downlink OFDMA system impaired by multicell interference. As recommended for WiMAX, we assume that the first part of the available bandwidth is likely to be reused by different base stations (and is thus subject to multicell interference) and th...
متن کاملResource Allocation in Downlink MIMO-OFDMA with Proportional Fairness
A new scheme for MIMO-OFDMA (Multiple Input Multiple Output Orthogonal Frequency Division Multiple Access) downlink resource allocation is presented in this paper. It has an objective of maximizing the total system capacity while having constraints on the total available power and proportional fairness. Dominant eigenchannels obtained from MIMO state matrix are used to formulate this scheme wit...
متن کاملSecurity-Aware Max-Min Resource Allocation in Multiuser OFDMA Downlink
In this paper, we study the problem of resource allocation for a multiuser orthogonal frequency-division multiple access (OFDMA) downlink with eavesdropping. The considered setup consists of a base station, several users and a single eavesdropper that intends to wiretap the transmitted message within each OFDMA subchannel. By taking into consideration the existence of the eavesdropper, the base...
