The article first analyzes the transmission characteristics of military light-line transmission and analyzes the line coding of high-speed digital subscriber line (G.shdsl), the latest DSL technology standard. The superior performance of the new technology in transmission distance and speed is Which is inseparable from the high-efficiency encoding method adopted by the author. In this paper, the coding gain of TC-PAM coding and the transmission characteristics of G.shdsl technology on military light-weight covered wires are theoretically analyzed, and the error rate and signal- The influences of various noises on the line characteristics are analyzed. Finally, the simulation results of the system transmission characteristics are given based on the above theoretical analysis, and the prospect of the next research is put forward for the special applications in the field.
