A statistical model for microcellular multipath propagation environment

Multipath propagation characteristics are of great importance in evaluating the performance of digital systems and designing wireless links. This paper describes statistical multipath propagation modeling for microcells in indoor, pedestrian, and vehicular environments. The channel impulse response is measured to clarify the statistical characteristics in urban areas, residential areas and indoors. The measuring channel sounder is the sliding correlator using 30 Mbit/s PN code with center frequency of 2.6 GHz. The measurements clarify the features of delay profile, mean RMS (root mean square) delay spread and local (or instantaneous) RMS delay spread. Furthermore, tapped-delay-line parameters for multipath propagation simulators based on this modeling are proposed. The proposed model is applicable to the evaluation of transmission characteristics of wireless digital communication systems in multipath fading environments.
