Code Generation that Minimizes Error Propagation

Code Generation that Minimizes Error Propagation

Method of Code Generation that Minimizes Error Propagation

When transmitting binary data, encoding schemes make the resulting waveform more immune to noise and interference. One class of transmission codes, block or line codes, are used to modulate binary symbols 0 and 1. There is a need to minimize error propagation in a line code, subject to information rate, one’s density, and maximum run length. This technology generates a line code so that error propagation is minimized. Other alternatives create more work by increasing the output error rate; this method, however, works with existing error Correction Codes by presenting a lower number of errors.
