Abstract

Abstract:

Based on common used recursive maximum expansion method, a resource allocation method is proposed for clustered discrete Fourier transform spread orthogonal frequency division multiplexing (DFTsOFDM) systems in 3rd generation partnership project long term evolution (3GPP LTE)．Simulations show that, if the number of clusters for each user can be increased without considering the impact of peaktoaverage power ratio, the flexibility of resource allocation is increased, it will lead to a higher spectral efficiency of system．

Key words: clustered discrete Fourier transform spread orthogonal frequency division multiplexing, resource allocation, 3rd generation partnership project long term evolution
