Abstract

Abstract:

In this paper, the requirements of inter-cell interference(ICI) cancellation to OFDM system design are investigated. Beyond that, a frequency resource block allocation approach based on coding block segmentation is introduced to adapt to different required bandwidths. Furthermore, a hybrid approach combining ICI cancellation and coordination is proposed to maximize the cell-edge and overall system spectral efficiency.

Key words: ICI, frequency resource block allocation, ICI cancellation, ICI coordination
