Novel approaches for downlink performance analysis in CDMA networks

Compared to uplink (UL), the analysis on downlink (DL) is much more challenging because of the DL power allocation problem. In this paper, we propose some new theoretical approaches to investigate the DL system performance. A new investigation approach for the DL pole capacity, which is based on the total transmission power, is presented firstly. Additionally, a simple theoretical analysis in the downlink power increase estimation due to new or modified bearer for real and nonreal time traffic service is described. Furthermore, an advanced downlink power allocation, based on the dynamic control of the maximum code power, is proposed. An advanced static system level simulator to evaluate capacity is developed. By comparing our analytical results with simulations, we show that our analytical approaches have very good match with simulation results.
