Abstract
This paper introduces the unequal protected channel codes, in which Turbo code is applied, for AMR speech services in 3G system. To investigate the link adaptation of AMR, an unequal power assignment strategy for 3G system was proposed, and analyzes the influence of AMR modes on the admission capacity of the cells was analyzed. Based on link-level simulations and the analysis of cell capacity, the link-configuring and mode-switching regulations of AMR speech service are summarized for 3G system, which are meaningful for radio resource management in practical systems.
