Performance characteristics of multicode CDMA downlink with systematic convolutional (Turbo) coding are obtained under shadowed multipath fading mobile channel. Two different iterative decoding methods are compared in two different synchronous downlink schemes operating under given channel conditions with the same transmission bandwidth as in IS-95. Multicode CDMA with LogMAP decoding is observed to provide better QoS with lower bit and frame error rates, reasonable complexity and shorter decoding delay compared to DS-CDMA downlink with single code pair assigned to each user.
