Abstract :
Serial concatenated convolutional coding with iterative decoding is examined for data transmission over the downlink of a W-CDMA system employing BPSK modulation and coherent RAKE receiver. Performance of serial concatenated convolutional coding is studied in a frequency selective Rayleigh fading channel. The effect of correlated fading on the performance of the proposed system is investigated by considering external block interleaver delays of 10 and 100 ms at mobile speeds 5 and 100 km/h. Simulation results show that this coding scheme achieves very good performance, outperforming conventional convolutional codes
