Turbo codes have a performance that approaches the Shannon limit on the capacity of a band limited communication channel. The transmission performance of nongeo services is mainly impaired by rapid amplitude and phase fluctuations of the received signal (fading). In this paper, the performance of turbo codes with different code parameters in slow and fast fading is presented for this channel. Because of the interleavers these codes offer some immunity to the correlated signal disruptions effects. So, as will be shown the effect of code length increment is greater than other parameters.
