    Abstract: Provided is a communication method for radio frequency identification (RFID). In order to transmit a command message with respect to an RFID tag, an RFID reader generates a command message comprising a command code indicating a type of command to be delivered to the RFID tag, a response format having one or more bits for indicating a type of additional data to be added to a response message to be received from the RFID tag, and an identifier identifying the RFID tag; and transmits the command message to the RFID tag, thereby allowing the RFID tag to immediately transmit the additional data via the response message in response to the command message.

    Abstract: A multistage channel estimation method and apparatus is provided. The multistage channel estimation method includes: receiving a data frame to compensate for a distortion of the data frame based on a first channel estimation value associated with a corresponding section of the data frame; a first step of changing the corresponding section to calculate a second channel estimation value associated with the changed section; a second step of updating the first channel estimation value based on the calculated second channel estimation value; a third step of compensating for the distortion of the data frame based on the updated first channel estimation value to count a number of compensations; and repeating the first step through the third step, when the counted number of compensations does not match a predetermined numerical value.
