Abstract:
1. A wireless communication apparatus comprising: a local oscillator that generates a plurality of LO signals corresponding to frequencies of a plurality of input RF signals; a code generating unit that generates a code group including a plurality of codes; a first multiplier that multiplies the code group generated by the code generating unit and the plurality of LO signals generated by the local oscillator to generate a plurality of first multiplication signals; an accumulator that accumulates the plurality of first multiplication signals generated by the first multiplier to generate an accumulated signal; a mixer that mixes the plurality of RF signals and the accumulated signal generated by the accumulator to generate a plurality of base band signals; a first signal processing unit that executes a signal process with respect to the plurality of base band signals generated by the mixer; a second multiplier that multiplies the plurality of base band signals processed by the first signal processing unit and the code group to generate second multiplication signals; and a second signal processing unit that executes a signal process with respect to the second multiplication signals generated by the second multiplier.
