D'JESUS, Germán; GUZMAN, Víctor; DOSTERT, Klaus  y  KAROLS, Pavels. DESIGN OF A CHANNEL EMULATOR SIMULATION OF THE LOCAL TRANSPORT SYSTEMS FEEDER LINES. uct [online]. 2007, vol.11, n.45, pp.183-191. ISSN 1316-4821.

This work presents a description in VHDL of a channel emulator circuit Developer for power line data transmission channels (PLC) for the 750 VDC power lines of urban transport systems (tramways). These emulator circuits are required for the development and testing of future communication systems in real time in the laboratory. To develop the Emulator a model of the urban transport power network behavior is presented, the different possible interference forms are characterized, and the functional blocks that emulate each interfering element are synthetized. Finally the model is assembled and the validation proofs are presented. The tests probe that the proposed Emulator reproduces the power line channel properties in terms of their high frequency data communication.
