Abstract
In this Letter a method is presented for measuring the main parameters required to estimate the capacity of the radio channel for wide‐band communications as the root‐mean‐square time delay and the coherence bandwidth. This method is based on the possibility of estimating the power‐delay profile from the knowledge of only the module of the transfer function of the channel in conjunction with the Hilbert transform. The major advantages of the method are first, the possibility to experimentally characterize the wide‐band channel performance by employing widely used and low‐cost instrumentation, and second, the possibility to extend the technique to outdoor radio channels. The error associated with the approximated method is quantified, so that it can be used from an engineering point of view in the planning and development of wide‐band wireless communications systems. © 2002 Wiley Periodicals, Inc.
