Abstract
A receiverreceives a wireless signal of, for example, an RFID system that conducts communication with a wireless signal based on reflection modulation. A demodulation blockdemodulates the received signal obtained at the receiverwith orthogonal demodulation. A display blockprovides signal points derived from the orthogonal demodulation onto an orthogonal coordinate display to display characteristics of the reflection modulation concerning an RF tag that conducts the reflection modulation of the wireless signal. The display of the signal points may have vector display or at least numerical values indicating magnitudes of the vectors. The processed results may be stored and signal points based on the stored results may be displayed on the orthogonal coordinate to compare sets of the characteristics of the reflection modulations on the display.
