Simulink and Stateflow model of IS-95A CDMA reverse traffic channel power control. Includes reverse traffic channel physical layer, together with open and closed loop algorithms for base station and mobile implemented as state machines with Stateflow

A closed-loop power control system having both fixed-step and adaptive-step power control algorithms and incorporating with multitap RAKE receivers was proposed. Simulations were performed for wide-band radio channels having path loss, slow
