<P>PROBLEM TO BE SOLVED: To provide a reception apparatus capable of A/D converting an I signal and a Q signal at optimal symbol timings. <P>SOLUTION: A quadrature demodulation unit 1 for analog outputting demodulates a quadrature modulated signal and outputs an I signal of an in-phase component and a Q signal of a quadrature component orthogonal with said in-phase component. An A/D converter 4 and an A/D converter 5 digitally convert the I signal and Q signal outputted via an LPF 2 and an LPF 3, respectively. A phase shifter 7 and a phase shifter 8 independently output A/D converted clocks to the A/D converter 4 and the A/D converter 5, respectively based on phase data from a phase data setting unit 9. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
