Phase noise effect on HIPERLAN/2 system performance

Abstract

The paper analyses the performance of the HIPERLAN/2 system as the phase noise due to a receiver's instability is introduced. Signal degradation is looked at by providing graphs of degradation (dB) against the E/sub b//N/sub 0/ (dB). We also look at the effect of phase noise variance on the signal-to-noise ratio of the signal. Some discussion about the oscillator phase noise mask type to be used in HIPERLAN/2 to achieve acceptable signal-to-noise ratio under the phase noise effect is provided. Lastly, the effect on system performance of phase noise due to the fading channel is investigated. All four modulation types (BPSK, QPSK, 16 QAM, 64 QAM) are modelled where the appropriate phase noise is added depending on the modulation scheme used.
