Abstract:
A method of transmitting information between units of a divided radio link, both units containing means of transmitting information to a cable and of receiving information arriving from the cable, the method comprising:applying a supply DC voltage V via a diplexer to the cable at one end of the cable and extracting the supply DC voltage V from the cable via a diplexer at an opposite end of the cable; supplying a base band transmission signal to a hybrid circuit which transmits the base band transmission signal via at least one of the diplexers to the cable; conducting a received base band signal carrying information of an original signal arriving from the cable via at least one of the diplexers to said hybrid circuit, which transmits the received base band signal to a receiver; and shaping the received base band signal using both analog and digital signal processing in order to form a representation of the original signal, wherein base band transmission and received signals travel in full duplex form in the same cable as the supply DC voltage V.
