Abstract: Disclosed herein are a tag transmission apparatus and a signal transmitting method thereof. The tag transmission apparatus converts a plurality of data bits into a symbol, which is one of a plurality of symbols, and multiplies the converted symbol by a square-wave having a predetermined frequency to thereby generate a subcarrier signal. Here, in the case in which the plurality of data bits are n (n is a natural number larger than 2) bits, the number of the plurality of symbols is 2n.

Abstract: A tag apparatus communicating with a reader acquires a command from a signal that is received from the reader, converts data corresponding to the acquired command to a plurality of multi-level parallel data, and generates a plurality of tag load impedances based on bias voltages that are mapped to correspond to each level of the plurality of parallel data. Therefore, a signal having electrical energy corresponding to the plurality of tag load impedances is transmitted to the reader.
