Wideband measurements for Multimedia Wireless System radio links

Abstract

The results of a measurement campaign conducted to determine the wideband behavior of the radio channel assigned to Multimedia Wireless Systems (MWS) are described in this Letter. It has been found that small multipath components are present in the impulsive response of radio channels operating at 40 GHz with 80‐MHz bandwidths. Multipath and delay spread are limited by the spatial filtering of directive antennas used in MWS and the low reflection coefficient of building materials at these frequencies. © 2002 Wiley Periodicals, Inc.

Study of wideband propagation in millimetric band

“…A Swept-Time Delay Cross-Correlation (STDCC) sounder was built to carry out the measurement campaigns [1]. This STDCC sounder transmits a PRBS sequence with a chip rate of 12.5ns.…”
