Performance analysis of CPCH-type packet channels for variable-bit-rate applications

This work gives an analytical performance measure of the common packet channel (CPCH) in 3rd Generation Partnership Project (3GPP) wideband code division multiple access (W-CDMA) systems. The CPCH procedure of the channel assignment (CA) mode is modeled as an Erlang loss network, and a technique for analyzing Erlang loss networks is applied to get the expression of the system throughput and delay. The theoretical results are verified with computer simulations.
