Abstract:

This work presents the coder and decoder of block 7B8B simplified with auxiliary channel. The coder 7B8B converts an input 7 bits word in an output 8 bits word. It transmits approximately an equal number of 1’s and 0’s to provide a DC constant component. It increases the transitions number, improves the system quality and security. The objective is also to improve the system potentialities with an auxiliary channel to monitor the communication (alarm.) The main channel is real, but the auxiliary channel is fictitious.
