HIPERLAN performance analysis with dual antenna diversity and decision feedback equalisation

To meet the increasing need for high capacity indoor wireless applications, the European Telecommunication Standards Institute (ETSI) have defined a new wireless LAN format. This system, known as HIPERLAN (High Performance Radio LAN), operates at 5.2 GHz and supports instantaneous bit rates of just under 24 Mb/s. The performance of the HIPERLAN physical layer is investigated and in particular, the advantages of dual antenna diversity explored. Five different combining schemes have been studied and both the LMS and RLS adaptation algorithms are considered in the analysis. The results indicate that with suitable combining, a BER⩽10^-4 is possible with RMS delay spreads of up to 100 ns using a (6,5) DFE and of up to 150 ns using a (8,7) DFE
