Application of Steiner design for capacity enhancement of frequency hopping spread spectrum wireless systems

Abstract

A slow frequency hopping code diversity system with a bandwidth-efficient modulation scheme based on balanced incomplete block (BIB) design - the Steiner design - has been proposed. The proposed system uses more than one frequency bin simultaneously to transmit a symbol. The system performance is evaluated and compared with the MFSK slow frequency hopping code diversity system for a multiuser environment considering non-fading and frequency non-selective slowly time varying Rayleigh fading channels. The performance has also been studied with matched frequency hopping (MFH), an efficient addressing technique for slow frequency-selective dispersive channels.
