    • PROBLEM TO BE SOLVED: To improve the accuracy of the process of demodulating signals transmitted by a MISO method.
      SOLUTION: An AND circuit 44 operates an ANDing of a CP flag from a CP flag generation portion 41, a sum CP flag from a sum CP flag generation portion 42, and a MISO flag from a P1 detection block, and if a CP signal detected from an OFDM signal is a Sum Pilot signal and if a transmission/reception method is the MISO method, supplies a correction value calculation part 36 with an enable signal in synchronism with the target OFDM signal. When the enable signal is input in synchronism with the OFDM signal, since the OFDM signal becomes the Sum Pilot signal of the CP signal, the correction value calculation part 36 supplies a correction circuit with a correction value corresponding to the phase of the sum pilot signal. This invention is applicable to the reception apparatus which receives signals transmitted from a plurality of transmission apparatuses by one antenna.

    • 要解决的问题:提高通过MISO方法发送的信号的解调处理的精度。 解决方案:AND电路44对来自CP标志产生部分41的CP标志,来自和CP标志产生部分42的和CP标志和来自P1检测块的MISO标志进行操作,并且如果 从OFDM信号检测的CP信号是和导频信号,并且如果发送/接收方法是MISO方法,则向校正值计算部36提供与目标OFDM信号同步的使能信号。 当使能信号与OFDM信号同步输入时,由于OFDM信号变为CP信号的和导频信号,所以校正值计算部36向校正电路提供与和导频信号的相位相对应的校正值 。 本发明可应用于接收从一个天线从多个发送装置发送的信号的接收装置。 版权所有(C)2011,JPO&INPIT
