New algorithm for Turbo decoding over correlated block fast fading channel

With the knowledge of correlated block fast fading channel, a new Turbo decoding algorithm is proposed. And from the algorithm, it is concluded that the mean and variance of signal-to-noise ratio are important to the performance. The simulation results show that the proposed algorithm can bring out about 2.9dB code gain over the scheme which adopts convolution code. Also the performance with the proposed algorithm is very good under the condition of significant mean and small variance of the signal-to-noise ratio.
