Performance Analysis of BPSK with Errors and Erasures Decoding to Mitigate the Effects of Pulse-Noise Interference

The performance of a system utilizing a binary phase-shift keyed waveform transmitted over a frequency-selective, slowly fading, Nakagami channel with pulse-noise interference in addition to additive white Gaussian noise is examined. The underlying information bits are assumed to be convolutionally encoded prior to transmission over the channel, and the receiver is assumed to use errors-and-erasures Viterbi decoding. The performance obtained with errors-and-erasures decoding is compared with the performance obtained with errors-only hard decision Viterbi decoding as well as soft decision Viterbi decoding
