Learning-based Block-wise Planar Channel Estimation for Time-Varying MIMO OFDM
Chenchen Liu, Wenjun Jiang, Xiaojun Yuan
In this paper, we propose a learning-based block-wise planar channel estimator (LBPCE) with high accuracy and low complexity to estimate the time-varying frequency-selective channe…
