Turbo coding in DVB — RCS standard over the stratospheric communication channel
The statistical model is used for analysis of the characteristic over the stratospheric communication channel, the structure and algorithm of Turbo encoding and decoding in DVB - RCS are studied, the encoder and decoder over the stratospheric communication channel are established using Turbo coding in DVB - RCS. Numerical results show the effects of different interleaving depth and different interleaving length on the properties of channel, the channel capacity and different coding rates of Turbo code in Rayleigh fading using QPSK modulation are simulated too.
