Abstract

The coexistence network of different 3G technologies (WCDMA and cdma2000) requires analysis of its adjacent channel interference. In this paper, we investigated the interference on WCDMA system that caused by cdma2000 network. Several scenarios and calculation models were applied to measure impacts on uplink and downlink scheme. The results showed that interference from cdma2000 influence WCDMA performance significantly. Distance between coexistence terminals (MS and BS), their number, and guard band frequency determined minimum allowed received power at WCDMA BS and SIR in WCDMA MS, which lead to capacity degradation
