Abstract
Plural n-symbol codewords are helically interleaved and transmitted in a stream. A receiver views the transmitted stream through n time windows, each time window having a length accommodating the longest anticipated decorrelation time of the channel. Individual equalizers process the data in individual windows. The n windows simultaneously furnish the n symbols of each codeword to an error correction decoder. The n equalizers respond to feedback in which the output of the decoder is substituted in place of undecoded symbols from the n windows whenever available.
