Patent ID: 7881668

Claim:
A receiving apparatus for receiving radio signals including image information transmitted by a mobile transmitting device through a plurality of receiving antennas, comprising: a plurality of frequency converters for outputting modulated signals obtained by converting respective radio signal received through the plurality of receiving antennas by different modulation frequencies; a superposing unit for superposing each of the modulated signals generated by the plurality of frequency converters on a frequency axis; a cable with a single coaxial cable where each of the modulated signals superposed by the superposing unit is transmitted; and a receiving unit for demodulating each modulated signal input through the cable to receive and output the image information; wherein the receiving unit includes: a plurality of demodulating units for demodulating the respective modulated signals output from the superposing unit to output base band signals thereof; and a signal processing unit for generating a base band signal having a high likelihood based on the plurality of the base band signals output from the demodulating units, and generating and outputting image information based on the base band signal.
