Abstract :
In this paper, an analytical model for expected convolutional code performance for IS-95-A CDMA systems is given. This model incorporates both the aspects of random and deterministic puncturing associated with IS-95-A, and variable rate source coding which is utilized in IS-95-A CDMA. As a result of this analysis, particular implementation issues are addressed for channel decoding in IS-95-A
