| Abstract: | The small-scale multipath propagation characteristics of the wireless channel at 3.5GHz was studied in a typical outdoor urban environment. A channel measurement platform was developed for the measurement. Both the fixed and mobile scenarios were measured;the power delay profile (PDP),the tapped delay line model,the multipath distribution,the mean excess delay and the Ricean K-factor were presented. The results verify that it is a rich scattered environment fit for multiple antenna wireless communications. |
