Leveraging GRU Networks for Robust and Efficient Vehicular Channel Estimation

IET Communications, Volume 20, Issue 1, January/December 2026.
Precise channel estimation becomes vital in robust vehicular communication, particularly in high‐mobility scenarios where conventional techniques such as Least Squares (LS), Minimum Mean Square Error (MMSE), Data Pilot‐Aided (DPA), and Orthogonal Matching Pursuit (OMP) methods frequently fail owing to error propagation and computational inefficiencies.
