Abstract
In this paper, various kinds of high throughput turbo decoding schemes are introduced, and a new turbo decoding scheme using the advantages of each scheme is proposed. The proposed scheme uses the decoding structure of double flow scheme, sliding window scheme and shuffled turbo decoding scheme. Simulation results show that the proposed scheme offers a BER performance equivalent to those of existing turbo decoding schemes with less clock cycles. We also show that the required memory can be reduced by choosing proper size of sliding window. Consequently, we can design a high throughput turbo decoder requiring low power and low area.
