It is an inevitable trend that the CDMA systems combine with the IP network. Realizing the IP-based CDMA systems brings many challenges, among which is the design of soft handoff. In soft handoff, data should arrive in a synchronized way for combination. However, the uncertainty of the transmit delay in IP network is inherent. The contradiction is a key problem in realization. This work presents a double-loop feedback algorithm to resolve this problem, and an improved one is also provided.
