We present a new technique to construct sliding-block modulation codes with a small decoding window. Our method, which involves both state splitting and look-ahead encoding, crucially depends on a new, ''local'' construction method for bounded-delay codes. We apply our method to construct several new codes, all with a smaller decoding window than previously known codes for the same constraints at the same rate.
In this correspondence we describe a generalization of the state-splitting algorithm (also known as the ach algorithm) for constructing encoders which encode arbitrary data into constrained systems of sequences. In th...

In this correspondence we describe a generalization of the state-splitting algorithm (also known as the ach algorithm) for constructing encoders which encode arbitrary data into constrained systems of sequences. In the generalized algorithm, we replace approximate eigenvectors with approximate eigenmatrices to yield a framework for designing encoders with smaller sliding-block windows and therefore lower error propagation.
