| Abstract: | How to improve the efficiency of radio resources which attracts a lot of interest becomes a hot spot problem.The cognitive radio(CR) technology is a new method for solving this problem.And the Non-Contiguous Orthogonal Frequency Division Multiplexing (NC-OFDM) technology provides a good platform for CR systems because of its agile choice mechanism of frequency.This paper introduces a novel adaptive dynamic resource allocation scheme for NC-OFDM based CR system.In this scheme,the secondary users choose their... |
