Analysis of impulse response measurements for PCS channel modelling applications

Impulse response measurements for personal communication services (PCS) were taken in the 1850-1990 MHz band in three outdoor macrocellular (cell radii of 5 km) environments: flat rural, hilly rural, and urban high-rise. The data were analyzed to provide information to assist in the development of radio propagation channel (especially tapped delay line) models for PCS applications. Analyses included number of paths, path arrival time, and path power statistics. Results of the analyses were found to be highly dependent on the threshold level used in processing. The urban high-rise cell showed a far greater number of paths than the rural cells for threshold levels 20 and 10 dB below the normalized peak of the power delay profiles.<
