TAG TRANSMISSION APPARATUS AND SIGNAL TRANSMITTING METHOD THEREOF |
| 摘要 |
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. |

1. A method of modulating and transmitting a plurality of data bits by a tag transmission apparatus, the method comprising:
converting the plurality of data bits into a first symbol, which is one of a plurality of symbols; multiplying the first symbol by a square-wave having a predetermined frequency to thereby generate a first subcarrier signal; and transmitting the first subcarrier signal to a reader, wherein 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. |
