An event detection system for a vehicle includes a transmitter and a receiver. The transmitter is disposed at a first position adjacent to a boundary of a space provided in the vehicle, including a first antenna having a transmitting direction, and the receiver is disposed at a second position adjacent to the boundary, which communicates with the transmitter and includes a second antenna having a receiving direction. The transmitter sends a probe signal toward the transmitting direction, and the receiver receives the probe signal. The receiver stores preset CSI. The preset CSI includes a first CSI and a normal CSI, the receiver obtains a current CSI from the probe signal by performing a time-reversal process, and to compare the current CSI to the preset CSI. When the first CSI is matched to the current CSI, a first event associated with the vehicle is determined to be occurred.

Event detection system and method for vehicle

A communication device includes a smart antenna, a storage device, and a processor. The smart antenna is capable of switching between a plurality of antenna modes. In each of the antenna modes during a training stage, the smart antenna receives a first feedback datum, and the processor calculates a reward indicator according to the first feedback datum. The processor compares all of the reward indicators with each other and controls the smart antenna to select a specific mode of the antenna modes according to a comparison between all of the reward indicators. In the specific mode, the smart antenna receives a second feedback datum, the processor determines the weight function of the first feedback datum and the second feedback datum of the specific mode, and the processor updates the reward indicator of the specific mode according to the weight function.

Communication device and antenna selection method

A detection device for communicating with an external device includes a smart antenna, a storage device, and a processor. The smart antenna is capable of switching between a plurality of antenna modes. In each of the antenna modes, the smart antenna transmits a test datum and receives a feedback datum according to the test datum, the processor performs a time reversal algorithm to the feedback datum so as to obtain a time reversal datum, the processor calculates an indicator according to the feedback datum and the time reversal datum, and the storage device stores the feedback datum, the time reversal datum, and the indicator. The processor compares all of the indicators with each other and controls the smart antenna to select the final mode of the antenna modes according to a comparison between all of the indicators.
