Performance of serially concatenated convolutional codes in the presence of pulsed noise interference and Rayleigh fading with DPSK modulation

In this paper, the bit error rate (BER) of a four-state serially concatenated convolutional code (SCCC) with AWGN and pulsed noise interference and DPSK modulation transmitted over Rayleigh fading channels is examined. For low signal-to-noise ratios (SNR), simulation results are obtained, while for higher signal-to-noise ratios, an average upper bound is developed. Results showed that Rayleigh fading is not as detrimental to a system utilizing SCCC as it is to one without SCCC. Similar to the non-fading case, pulsed noise interference is more effective for higher signal-to-interference noise ratios (SIR).
