Exclusive Region Based Scheduling for MB-OFDM UWB Using Hidden Pilot Sequences

Abstract

This paper deals with an exclusive region (ER)-based scheduling scheme in multiband orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) with hidden pilot sequences. Deriving a generalized radius for the ER using information of statistical topology, a novel scheduling approach that uses a radius for the ER is introduced. Numerical results show that scheduling that is based on proposed ER radius can always outperform the time division multiple access (TDMA) scheme with respect to network throughput and the proposed approach to the radius of the generalized ER provides better scheduling performance than the radius of the conventional method.
