With high terminal velocity, the time-varying channels being encountered making its coherence time is small enough to be compared with symbol duration. Hence a severe degradation in estimation process is being registered with conventional frame structure of LTE system where pilot symbols are introduced in each 0.5ms. This paper has proposed a frequency domain estimation updating algorithm to track the time-varying channel parameters and generate updated estimates in each payload symbol without any additional spectral overhead. A significant improvement in system performance in high-speed environment is registered.}, number={2}, journal={Asian Journal of Applied Sciences}, author={Bandopadhaya, Shuvabrata}, year={2016}, month={Apr.} }
