Proportional Resource Allocation in OFDMA Systems Based on Weighted Normalized User's CSI Robin SHRESTHA Jae Moung KIM Publication IEICE TRANSACTIONS on Communications Vol.E95-B No.6 pp.2137-2140 Publication Date: 2012/06/01 Online ISSN: 1745-1345 DOI: 10.1587/transcom.E95.B.2137 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Wireless Communication Technologies Keyword: resource allocation, OFDMA, CSI, scheduling scheme, Full Text: PDF>>
Summary: We formulate the resource allocation problem to maximize the sum rate, subject to constraints on total power, bit error rate, and rate proportionality among the users for proportional resource allocation in orthogonal frequency division multiple access (OFDMA) systems. For this we propose a novel scheduling scheme based on weighted normalized user's channel state information (CSI). We then adopt the linear power distribution method and waterfilling technique to allocate power among the users and across the subcarriers respectively. | |||||
