Abstract

The HIPERLAN system will operate in the 5 GHz and the 17 GHz bands at a data rate of >23.5 Msymbols. Access to the radio medium is assumed to be asynchronous and the medium to be a Rayleigh fading channel. These would need a robust, synchronization mechanism, so that both timing instants in the receiver can be chosen and equalization performed to mitigate the effects of the time dispersive channel. Results show that the codes perform well under moderately severe channel conditions. An optimum 16 bit sequence was selected for appending to the start of frame synchronization sequence to make up for the full 48 bit training sequence. The added sequence preserves the desired correlation function properties of low sidelobes and zero imaginary part.
