Title:
信号検出システム及び方法
Document Type and Number:
Japanese Patent JP6967619
Kind Code:
B2
Abstract:
A system and a method for signal sensing are provided. The system for signal sensing includes a processor, a transmitter, a receiver, and an oscillator. The oscillator is coupled to the transmitter and the receiver. The oscillator generates a clock signal. The transmitter transmits a plurality of output signals according to the clock signal. The receiver receives a first output signal reflected by an object according to the clock signal and obtains a channel state information according to the first output signal. The processor identifies a state of the object according to the channel state information and outputs the state of the object.
