Detailed Documentation
This article presents a comprehensive approach to simulating channel coding in CDMA2000 systems using MATLAB's Simulink environment. The implementation primarily concentrates on Turbo coding components, which involve parallel concatenated convolutional codes with interleavers. The simulation model incorporates key elements such as recursive systematic convolutional (RSC) encoders, pseudo-random interleavers, and iterative MAP (Maximum A Posteriori) decoding algorithms using the BCJR method. For optimal performance and compatibility, it is recommended to use MATLAB version 7.0 or later to access all Simulink library components and ensure proper execution of the Turbo coding simulation blocks. The model demonstrates practical implementation of coding parameters specified in CDMA2000 standards, including code rates and frame structures relevant to forward and reverse link transmissions.
