Abstract:
1. A receiving apparatus comprising: RF filters for selecting and outputting a signal to be down-converted from among a plurality of received signals having different bands; a phase conversion unit for generating a phase difference between output signals of the filters and down-converting the output signals of the filters to output a plurality of sample signals; a quantization unit for converting the plurality of sample signals from discrete signals into digital signals; and a signal separation unit for separating and outputting each of a plurality of output signals corresponding to the plurality of received signals from the output signals of the quantization unit by using a phase shift value caused by the phase difference, wherein the plurality of received signals comprise a first received signal, a second received signal, and a third received signal, and the plurality of output signals comprise a first output signal corresponding to the first received signal, a second output signal corresponding to the second received signal, and a third output signal corresponding to the third received signal, and wherein the signal separation unit comprises:
