L-band (960 to 1164 MHz) Digital Aeronautical Communication Systems (LDACS) is a promising technology deployed to face the challenge of saturating Very High Frequency (VHF) (118 to 137 MHz) spectrum and spectrum congestion. Interference mitigation in LDACS from the interference caused by existing users is extremely important considering the safety of the aircraft. This paper proposes LDACS receiver prototype which employs a linear clipping method, known as deep clipping to reduce the interference from the legacy user Distance Measuring Equipment (DME). The performance of deep clipping is compared with the conventional pulse blanking, clipping and joint clipping blanking methods. The reduction in bit error rates (BER) of received signal with the employment of deep clipping and the comparison of same with conventional methods are done in Matlab. The simulation results disclose that deep clipping and joint clipping blanking outperformed the conventional clipping and blanking method. Also deep clipping has the best performance for optimum depth factor than other non linear preprocessors.
