基于索引调制的广义频分复用技术
GFDM with Interleaved Subcarrier-Index Modulation
摘要
Abstract
In order to reduce the interference and improve the system performances,this paper utilizes the idea of orthogonal frequency division multiplexing (OFDM) with interleaved subcarrier-index modulation (OFDM-ISIM) into Generalized frequency division multiplexing (GFDM),which is referred as interleaved subcarrier-index modulation GFDM (ISIM-GFDM).In the ISIM-GFDM,the data are mapped by the interleaved subcarrier-index modulation in each ISIM-GFDM subsymbol,which can enlarge the average Euclidean distance of the received symbols and improve the error performance of the signal recovery in the receiver.Simulation results show that ISIM-GFDM outperforms GFDM and SIM-GFDM in wireless mobile communication channel in terms of bit error rate (BER).关键词
