Abstract
A new decoding method is presented for permutation
codes obtained from distance-preserving mapping algorithms,
used in conjunction with M-ary FSK for use on powerline
channels. The new approach makes it possible for the
permutation code to be used as an inner code with any other
error correction code used as an outer code. The memory and
number of computations necessary for this method is lower than
when using a minimum distance decoding method.
