Motivated by interest in making delay announcements in service systems, we study real-time delay estimators in many-server service systems, both with and without customer abandonment. Our main contribution here is to consider the realistic feature of time-varying arrival rates. We focus especially on delay estimators exploiting recent customer delay history. We show that time-varying arrival ra...

This paper investigated a Subsample Time delay Estimation (STE) algorithm based on the amplitude of cross-correlation function to improve estimation accuracy. In this paper, rough time is applied traditional cross correlator, and fine achieved by approximating sampled sequence theoretical for linear frequency modulation (LFM) signal. Simulation results show that proposed outperforms existing me...

The estimation for the nonlinear dynamic system with time-varying input timedelay is an important issue for system identification. In order to estimate the dynamics of the process, a dynamic neural network with external recurrent structure is applied to the modelling procedure. In the case where time-delay is time varying, a useful way is to develop on-line time-delay estimation mechanisms to t...

Delay estimation is a difficult problem in computer networks. Round trip time (RTT) is often used as an approximation of the delay but, because it is a sum of the forward and reverse delays, the actual oneway delay cannot be estimated accurately from RTT. Accurate oneway delay estimation becomes crucial because it serves a very important role in network and application design. A new scheme is p...
