Improving the efficiency of detecting errors in data transmission lines with a pulse-amplitude modulation

Markovskiy A.P., Turchenko Y.A., Kovalchuk A.V.

In paper an approaches for increasing the effectiveness of error detection in computer network channels with Pulse-Amplitude Modulation (PAM) has been proposed. Proposed approaches are based on consideration of special feature of errors which are appearances in line with PAM. The first approach consist of CRC modification specifically for line with PAM. The second approach is base of weighted checksums using. The way for checksum components coding has been developed. It has been shown that proposed checksum modification ensure superior digital data control transformation reliability for channels with PAM in compare to CRC.
