Method and apparatus for encoding/decoding QAM trellis coded data
Ephraim Zehavi,Jack K. Wolf +1 more
TL;DR: In this paper, a method and apparatus for encoding and decoding QAM trellis modulated data is presented, where a subset of bits of an input bit set are convolutionally encoded based upon punctured convolutional codes of a lower data rate to provide a set of coded symbols.

Transmission of digital signals by orthogonal frequency division multiplexing
TL;DR: In this paper, an orthogonal frequency division multiplexing (OFDM) system using an outer Reed-Solomon encoder and interleaver (24) and an inner convolutional encoder (26) is described.

On saving decoder states for some trellis codes and partial response channels
Ephraim Zehavi,Jack K. Wolf +1 more
TL;DR: It is shown that under certain conditions, when convolutional codes with precoding are used in conjunction with a partial response channel, the number of decoder states in a maximum-likelihood decoder matched to both the code and channel is 1/2 of that predicted by J.K. Wolf and G. Ungerboeck.

Iterative decoding for concatenated error correction coding in PRML channel systems
TL;DR: A new iterative decoding scheme was developed for the cyclic redundancy check error correction code (CRCC), a concatenated error correction coding system, which improves the correction capability of the outer RS-ECC coding by making use of a CRCC coding for specific correcting short error-events.
