Survey on Dynamic Resource Allocation for Cognitive Radio OFDM System
摘要
Abstract
Cognitive radio is one of the primary schemes to deal with spectrum scarcity nowadays, and its combination with OFDM (Orthogonal Frequency Division Multiplexing) system draws great attention. In order to make full use of the scarce spectrum resources and transmission power and to relieve the situation, the paper summarized and analyzed the cognitive OFDM system regarding spectrum sharing strategy, unicast and multicast, fairness, relay-aided etc., introduced various resource allocation methods, studied the current situation of dynamic resource allocation research, and focused on the advantages and disadvantages analysis of each method. Finally the possible issues for future study in this ifeld were proposed.关键词
