The 12B8T multilevel line coding scheme in digital to digital data conversion

12B8T multilevel line coding scheme has been used as an alternative to traditional line coding schemes e.g. 4B3T, 8B6T schemes in digital to digital data conversion. Unipolar, polar, bipolar, multilevel and multiline schemes are used in line coding. But these approaches have some characteristics e.g. costly, no self-synchronization, DC-components, baseline wandering, high bandwidth etc. These characteristics are mainly known as the limitations of these line coding systems. In this paper, we introduced the 12B8T multilevel line coding scheme which eliminates no self-synchronization, DC-components and the performance of this scheme is better than 4B3T, 8B6T multilevel schemes in terms of speed of transmission, bandwidth, and signal rate.
