VICTIM SYSTEM DETECTION DEVICE, METHOD OF DETECTING A VICTIM SYSTEM, COMMUNICATION DEVICE AND COMMUNICATION METHOD

摘要

PURPOSE: A victim system detection device, a detection method thereof, a communications device, and a communication method thereof are provided to be implemented in a small area by detecting a victim system after calculating correlation in a frequency domain. CONSTITUTION: A victim system detection device(500) comprises a correlation part(510) and a determining part(520). The correlation part calculates correlation between a frequency domain baseband signal and a correlation sequence for a second communications system. The frequency domain baseband signal is generated by converting a wireless signal. The radio signal is received in a first communications system. The determining part determines whether the frequency domain baseband signal includes the signal of the second communications system based on the correlation.
