COHERENCE BANDWIDTH MEASUREMENTS IN AN INDOOR MICROCELL AT 62.4GHZ

Results of experiments made at 62.4GHz in a long narrow corridor to me asure the coherence bandwidth are presented. The correlation coefficie nts between envelopes separated in frequency are measured and expresse d as functions of distance between terminals. They are found to be hig hly variable with the location of the terminals in the microcell. From these data the frequency correlation function is computed and used to calculate the coherence bandwidth. The coherence bandwidths for corre lation levels of 0.5, 0.7 and 0.9 are given for 90% of the time.
