Abstract :
Mobile multimedia broadcasting could suffer from multipath fading as well as partial-time jamming interference. In this paper, turbo product codes are proposed to suppress the effect of these interferences. We propose an efficient decoding algorithm using Chase decoder by taking into consideration the jamming state information. To make the variance of the jammed bits same as the other un-jammed bits, a scaling factor is used to adjust the amplitude of the received signal of the jammed bits. This processing benefits the followed Chase decoder. The upper and lower bounds of turbo product codes over such channels are derived and simulations have been performed to evaluate the derived bounds. Simulation results have shown that the proposed algorithm can mitigate the partial-time jamming greatly and the numerical bounds are tight for high signal-to-jamming ratio region
