基于DFT-FB改进的F-OFDM方案
Improved F-OFDM scheme based on DFT-FB
摘要
Abstract
Due to using long subband filters to reduce the out-of-band emission(OOBE),the complexity of filtered-OFDM (F-OFDM) is very high.In order to solve this problem,based on the thoughts of filter bank processing,i.e.using polyphase network(PPN) to reduce the system complexity and filtering in each subcarrier to lower OOBE,this paper proposes subcarrier filtering technology of filter bank to improve F-OFDM.Compared with F-OFDM,the proposed scheme can obtain the same bandwidth efficiency and less implementation complexity.The simulation results also show that the proposed scheme can not only optimize the flexibility of system,but also improve the transmission performance and anti-channel fading ability in AWGN(additive white Gaussian noise) channel and fading channel.关键词
