<P>PROBLEM TO BE SOLVED: To easily and highly accurately measure reception quality of an equalized single-carrier signal in a frequency domain. <P>SOLUTION: A reception quality measurement apparatus includes: a first sub-carrier averaging part 13 for averaging equalized channel gain over sub-carrier and outputting the gain; a first power calculating part 13 for calculating the output power and outputting the power as signal power; a pilot replica generating part 14 for generating a pilot signal replica concerning a zero-timing signal component, based on a equalized zero-timing signal component and a predetermined pilot code characteristic, and outputting the pilot signal replica; a subtracting part 15 for subtracting the pilot signal replica from an equalized signal and outputting it as an interference signal; a second power calculating part 16 for calculating and outputting the power of the interference signal; a second sub-carrier averaging part 17 for averaging the power of the interference signal over the sub-carrier and outputting it as interference power; and a division part 18 for dividing the signal power by the interference power, and calculating the equalized reception quality. <P>COPYRIGHT: (C)2009,JPO&INPIT |
