Link budget of cdma2000 1xEV-DO wireless Internet access system

摘要

This paper presents the analysis and simulation results for a 1xEV-DO link budget. The traditional fixed rate CDMA link budget calculation has been extended to include link adaptation and multi-user diversity gains. The main conclusion is that 1xEV-DO provides a link budget advantage over IS-95-A of approximately 10 dB on the forward link and 1.5 dB on the reverse link.
