Abstract :
Transport channel synchronization in 3G access networks is currently based on a simple algorithm that tries to track the delay of the link by adding or subtracting a constant step. We propose an algorithm that improves the responsiveness of the system under abrupt delay changes, reducing frame losses. Our proposal is faster than the proportional tracking system upon which it is based and has delay-independent stability.
