Other embodiments are also disclosed herein.

An intelligent tracking system generally includes one or more tracking devices, some of which may be passive tracking devices. Each passive tracking device includes one or more transceivers and is energized by an energizing signal. Some of these passive tracking devices may operate in a first communication mode or a second communication mode based on the energizing signal. Some tracking devices may include encryption modules or authentication modules. Some of these devices may incorporate a bulk acoustic wave oscillator.

This information processing apparatus includes an instruction determining unit and a signal output unit. The instruction determining unit determines an instruction related to communication using a code image with an external apparatus. The signal output unit outputs, on the basis of the determined instruction related to the communication, a signal for controlling an operation related to communication of the external apparatus. Accordingly, high usability can be provided for communication with the external apparatus.

The information processing apparatus includes a receiving unit and a generating unit. The receiving unit receives purchase information generated on the basis of a payment operation using a user terminal for purchasing a target object, from the user terminal. The generating unit generates, on the basis of the received purchase information and predetermined rule information regarding giving of a reward, reward information regarding the reward depending on purchase of the target object.

A method for estimating channel parameters includes: sending a paging signal for identifying the tag device; sending training sequence information, receiving first training sequence feedback information during a non-working period of the tag device, receiving, during a working period of the tag device, second training sequence feedback information modulated by the tag device, and estimating the channel parameters of the tag device according to the training sequence feedback information and the second training sequence feedback information. The tag device having at least one antenna of the present disclosure can modulate carrier signals to transmit information, has advantages such as a fast transmission rate, a large amount of transmission data and a strong anti-interference capability, and can adapt to different application scenarios.
