Fig. 7From: EKF/UKF-based channel estimation for robust and reliable communications in V2V and IIoTBER for channel estimation methods in different taps and SNR environments. Under different SNRs, the BER under the BEM-EKF and BEM-UKF channel estimation methods can be stably maintained at a low level with the increase of the number of multi-paths, while the BER has changed a lot under the BEM-LS methodBack to article page
