'' process and apparatus for converting a signal of high frequency and broad band, digital, real in a set of signals to baseband digital complex.Processes and apparatus for processing a set of signals in a digital baseband complex signal of high frequency, broadband, digital filter, real, "ladder" digital bilinear, and.The base station in a radio system communication ''. A base station in a radio communication system uses filters pass band complex ( 87 ~ 1 ~ , 87 ~ 2 ~,..., 87 ~ n ~) and sub sampling for a broadband channel signal containing many channels or groups of channels.
