<p>PROBLEM TO BE SOLVED: To provide a base station receiver that realizes a low cost, enhanced noise immunity and a relieved load of a reception section or the like. SOLUTION: A parallel serial conversion section being a component of an output data conversion section 8 of the reception section 4 converts a base band reception data signal 20 from an analog/digital converter 112 into a serial signal and a differential output signal conversion section of the output data conversion section 8 converts an output signal of a parallel serial conversion section into a differential signal and outputs the differential signal to a transmission line 12. Then a differential input signal conversion section being a component of an input data conversion section 10 of a base band processing section 6 receives the differential signal through the transmission line 12, outputs a single serial signal, a serial parallel conversion section of the input data conversion section 10 converts the serial signal into a parallel signal and gives the converted signal to an inverse spread processing section 114. Thus, the transmission line 12 is configured to use two signal lines in pairs for the transmission of the differential signal and number of signal lines can considerably be reduced in comparison with the case of outputting a signal to the base band processing section directly from the analog/digital converter section 112.</p> |
