Subcarrier and power allocation
|Issue Date:||2008||Citation:||Da, B.,Ko, C.C. (2008). Subcarrier and power allocation in relay-assistant OFDMA cellular system. 2008 14th Asia-Pacific Conference on Communications, APCC 2008 : -. ScholarBank@NUS Repository.||Abstract:||In this paper, resource allocation problems in a downlink relay-assistant OFDMA cellular system are studied. Amplify-and-forward relaying strategy is utilized at each relay station to assist signal transmission while half-duplex transmission protocol is adopted. A joint optimization of subcarrier-pairing in two consecutive time slots and power allocation on each subcarrier in each time slot is investigated through a capacity maximization problem constrained on independently available power at BS and RS. Some fundamental principles to achieve optimality are given while a few subcarrier and power allocation algorithms are proposed. The performance of these resource allocation algorithms is evaluated by computer simulation. copyright © 2008 IEICE.||Source Title:||2008 14th Asia-Pacific Conference on Communications, APCC 2008||URI:||http://scholarbank.nus.edu.sg/handle/10635/71893||ISBN:||4885522323|
