Orthogonal Frequency Division Multiplexing (OFDM) suffers from the partial time-domain loss which is caused by obstacles and Impulsive Noise (IN) in harsh industrial scenarios such as automatic factories. The conventional methods include Partial Packet Recovery (PPR) and Blanking Nonlinearity (BN). PPR determines the erroneous part and re-send this part. However, PPR should have feedback and may have delay. BN selects the proper threshold to blank the signal which is affected by IN. However, it is sensitive to the threshold. In this pa- per, we utilize OFDM with Suboptimal Maximum Likelihood sequence estimation (SML) (OFDM-SML) to recover the received partial time-domain signal caused by obstacles. Moreover, OFDM-SML with BN (OFDM-SMLB) is proposed to further improve the performance of the conventional blanking system. |
