Abstract
A interleaver/de-interleaver mechanism for reducing the latency of transmitted interleaved codewords. The interleaver/de-interleaver mechanism utilizes a shortened first codeword which functions to offset the interleaving and transmission on subsequent codewords so as to achieve reduced latency depending on the degree of shortening applied. The interleaver/de-interleaver mechanism is particularly useful in power line carrier based systems to reduce the exposure to burst errors by providing interleaving with minimal latency penalty.
