This paper is concerned with some physical layer issues for HIPERLAN. First, the noise performance required of each class of receivers in HIPERLAN is determined. Secondly, the effect of frequency offset on the performance of equalisers is investigated and various techniques for joint equalisation and frequency offset compensation are studied. It is shown that by employing a decision feedback equaliser incorporating a second order phase locked loop, the effect of both the intersymbol interference and frequency offset can be significantly reduced. Using such a technique, the packet error ratio (PER) of a HIPERLAN radio link in a multipath channel is found by simulation.
