The Turbo-codes Performances in the (Radio) Rice Flat Fading Channels

The received signal from (radio) Rice flat fading transmission channels has both unfading (like in the AWGN –Additive White Gaussian Noise channel) and fading components (like in the Rayleigh channel). In this paper the BER (Bit Error Rate) and FER (Frame Error Rate) TCs (turbo codes) performances provided by the simulations of the way of the TCs work in the Rice flat fading (frequency unselective) channel, for different unfading and fading power ratio values, are presented. The 1/3 rate TCs, a S-type random interleaver with 1784 bits length, 15 iterations with a stop criterion, and the BPSK (Binary Phase Shift Keying) modulation have been used. The recursive systematic convolutional code with the constraint length K= 4 have been the implied component codes.
