Title:
無線通信装置および無線通信装置の周波数オフセット補償方法
Document Type and Number:
Japanese Patent JP6936381
Kind Code:
B2
Abstract:
A wireless communication device includes frequency hopping means for changing a radio frequency based on a temporarily defined pattern, and a frequency offset compensation unit. The frequency offset compensation unit includes a frequency offset calculator that calculates a frequency offset amount from a received signal, a hopping frequency value converter that uses the frequency offset amount, a radio frequency from which the frequency offset amount is calculated, and a transition destination radio frequency transitioned by the frequency hopping means to calculate an estimated frequency offset value for the transition destination radio frequency, and a rotator that uses the estimated frequency offset value for the transition destination radio frequency to perform phase rotation on the received signal.
