COHERENCE BANDWIDTH MEASUREMENTS IN A SUBURBAN MICROCELL AT 62.4GHZ

Results of experiments made at 62.4GHz to measure the coherence bandwi dth in a suburban mobile radio environment are presented. The correlat ion coefficients between envelopes separated in Frequency are measured and expressed as functions of distance from the base station. They ar e found to je highly variable with the location of the receiver in the microcell. I-rom these data, the frequency correlation function is co mputed and used to calculate the coherence bandwidth. Values of the co herence bandwidth for correlation levels of 0.5, 0.7 and 0.9 are given for 90% of the time.
