This paper conducted experiments to model the channel for digital transmission based on the analysis of the experimental results obtained, and revealed the characteristics of propagation loss, characteristics of delay path profile and the noise characteristics of the power line carrier system that uses power transmission lines. In terms of the characteristics of propagation loss, experimental results were subjected to multiple regression analysis and an equation to estimate propagation loss was derived with useful parameters. With the characteristics of delay path profile, additional loss of the delay path was modeled and clarified. It was indicated that delay path travel both by in-phase propagation and out-phase propagation, thus it is important to consider these two propagation characteristics when modeling. With the noise characteristics, it was indicated that they are superposition characteristics of thermal noise and impulse noise and these two characteristics were modeled based on theoretical examination and the cumulative probability distribution. Simulations using these derived models agreed well with the measurement results, indicating these models will be practical for use.
