cdma2000 Physical Layer in Simulink

Demonstrates how the Communications Toolbox™ can be used for: (i) working with standard-compliant cdma2000® waveforms in Simulink® and (ii) building standard-compliant decoder subsystems. Specifically, the model mainly covers the Forward Fundamental Channel (F-FCH) of the downlink channel between a base station and a mobile station for radio configuration 3 and spreading rate 1.
