Impact of Non-Gaussian Impulsive Noise and Multipath Fading on the Performance of Digital Mobile-Satellite Systems

The impact of non-Gaussian impulsive noise combined with that of Gaussian thermal noise on the performance of mobile-satellite systems is analyzed. The analysis if further extended with a co-channel carrier wave (CW) interference and/or multipath fading (m-distribution) presented in the transmission channels. The system performance is evaluated in terms of CNR, CIR (Carrier-to-interference Ratio), impulsive index of the noise, power ratio of the Gaussian noise-to-impulsive noise and fading figure. The impulsive noise may be caused by in-band or by out-of-band intermodulation noise which has a non-Gaussian probability density function.
