In this paper, we present modified IWS (M-IWS) interleavers that can further increase turbo decoding throughput only at the expense of slight performance degradation. By deriving the number of M-IWS interleavers, we demonstrate that the number is much smaller than that of IWS interleavers, whereas they both have a very simple algebraic representation. Further, it is shown by analysis that under given conditions, storage requirements of M-IWS interleavers can be reduced to only 368 storage bits for variable interleaving lengths. In order to realize parallel outputs of the on-line interleaving addresses, a low-complexity architecture design of M-IWS interleavers for parallel turbo decoding is proposed, which also supports variable interleaving lengths. Therefore, the M-IWS interleavers are very suitable for the turbo decoder in next generation communication systems with the high data rate and low latency requirements.
