Abstract

Wide-band frequency domain measurement and modeling of indoor radio channels at 5 GHz, for future HIPERLAN system are presented. Vector network analyzer is used to measure the frequency response of the channel. Impulse response profiles are obtained by using inverse Fourier transform. Empirical values of the RMS delay spread and number of multipath values are tested for normal distribution using Anderson-Darling goodness of fit test and the statistics are presented. For most of the cases, RMS delay spread values showed good fit to normal distribution, whereas the number of multipath values rejected the null-hypothesis that it follows normal distribution. Statistics of the RMS delay spread, number of multipath values and the coherence bandwidth are also presented
