الملخص

In this research parallel concatenated convolutional coding with iterative decoding is examined for data transmission over the downlink of a WCDMA system employing BPSK modulation and coherent Rake receiver. Performance of parallel concatenated convolutional coding is studied in a frequency selective Rayleigh fading channel, new type of external interleaver which is called Dithered Golden Section Interleaver (DGSI) is used. The effect of correlated fading on the performance of the proposed system is investigated by considering external block interleaver delays of 10 ms at mobile speeds 5 km/h. Simulation results show that the employing of this type of interleaver is outperforming at high signal to noise ratios the classical random interleaver.
