We investigate the systematic convolutional low density generator matrix (SC-LDGM) codes over Rayleigh fading channels with symmetric alpha-stable (S\(\alpha \)S) impulsive noise. The performance is analyzed by deriving a lower bound based on an equivalent genie-aided (GA) system. Numerical simulations show that the SC-LDGM codes can achieve a significant gain compared to the convolutional codes over Rayleigh fading channels with impulsive noise. Numerical results also show that the performance of the SC-LDGM codes can be around one dB away from Shannon limits at the bit-error rate (BER) of \(10^{-5}\) and matches well with the GA lower bound in the low BER region.
