Definition of APD-Based Emission Limits for the Protection of Coded Wireless Systems from Impulsive Interference

The definition of emission requirements in terms of amplitude probability distribution (APD) is studied for the protection of digital wireless systems with error correction coding. Focusing on coherent binary phase-shift keying with convolutional coding and Viterbi decoding, a simple approximation of bit error probability (BEP) is derived in terms of the APD for non-Gaussian interferences that can be modeled by Middleton's class A model. By using the BEP expression, discussion is made on how APD-based emission limits can be defined for protecting coded wireless systems from impulsive interferences.
