Abstract
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.
