Most of the research works carried so far concentrated on decoders and interleavers. The performance of Turbo codes depends on different constituent components such as encoder, decoder and interleaver with metrics of bit error rate and complexity. In this paper a new interleaver structure using sub interleavers is proposed to provide a faster turbo codes for channel with less effect of noise. The major concern of this work is to find an optimum number of sub interleavers which satisfies certain limits of bit error rate and processing time. The simulation was performed using MATLAB and the results shows that the processing time has been reduced to about 10% than the conventional block interleaver.
