Abstract

Vector OFDM was proposed by one of the authors for single-antenna systems as a generalization of OFDM. It converts an ISI channel into multiple "ISI-free" vector channels while involving channel matrices instead of channel coefficients in one-tap equalization. Over multipath fading channels, it benefits from signal space diversity. It either reduces the cyclic prefix data rate overhead or the peak-to-average power ratio. This paper addresses the issue of guard band configuration and provides a solution.
