Channel estimation method for MIMO-OFDM systems based on pilots and modified Kalman filter

Channel estimation method for MIMO-OFDM systems based on pilots and modified Kalman filter

A combined channel estimation method of time-frequency-selective fading channels in MIMO-OFDM systems was proposed.The time-varying channel was modeled as an autoregressive（AR） process and a low-dimensional Kalman filter based on pilots was used to estimate the AR parameters,and the LS（least square）...
