Reverse link capacity for mixed voice users (8 kbps and 13 kbps vocoders) in IS-95A networks

The reverse link capacity of a cellular network based on IS-95A CDMA interim standard is investigated. The results reflect various tradeoffs associated with having different rate set voice users (8 kbps and 13 kbps vocoders) simultaneously in the network. Different frame error rate choices for two rate sets lead to different performance. The tradeoffs associated with the variety of technical options show that much of the capacity can be gained back by choosing 3% frame error rate operating point for Rate Set II users.
