摘要：

The reverse link signal power and interference of a spectrally overlaid macro/micro cellular CDMA system supporting multimedia traffic is characterized in a typical propagation environment. Several narrowband subsystems are overlaid on a wideband subsystem in macrocells, while a single wideband subsystem is operated in a microcell with the same spectrum as the macrocell wideband subsystem. The required signal power and interference are analyzed in terms of the relative user signal power and the cross-tier interference factors between the macrocell and the microcell. Analytical results show that the dominant parameters affecting the system performance are the spectral overlay ratio and the distance between the microcell and macrocell base stations. These results can be applied to CDMA multimedia network planning in heavily populated traffic areas.
