In this paper, we propose a new channel interpolation algorithm for Massive Multiple Input, Multiple Output (MIMO) receivers. The algorithm employs adaptive linear interpolation for each channel tap separately in the time domain. It outperforms a common spline or linear interpolation due to considering more statistics (noise power and channel sparsity). The method is validated with a practical sparse channel estimation algorithm in both antenna and beam domains of 64 antennas receiver. Simulation results are presented for users, moving with a speed of up to 160km/h in line-of-sight scenarios (car in highway, fast train, quadcopter, and many others) of 5G QuaDRiGa 2.0 channel.
