Turbocodes

The fading phenomenon occurs in radio transmission channels. It is due to the presence of multipath that varies during the transmission. We analyze the performance in terms of Bit Error Rate and Frame Error Rate of a (multi-binary) turbo-coded system over frequency-nonselective fading multipath channels.
The multi-binary turbo code employed has the following configuration:
