□ Problem: Impulsive Interference towards LDACS1 ▹ LDACS1 works between two DME signals, and is influenced by the impulsive interference from DME. ▹ Blanking Nonlinearity (BN) at receiver is simple and effective for interference mitigation, but introduces inter-carrier-interference (ICI) to the OFDM-based LDACS1. □ Solution: Iterative Receiver Design ▹ We use iterative decoding (ID) between the Soft-Input Soft-Output (SISO) demodulator and decoder to reduce the negative effect brought by ICI. ▹ Iterative channel state information (CSI) estimation is also carried out to further improve the performance.
