Apparatus and method for transmitting tag |
| 摘要 |
Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader |

1. A method for transmitting a plurality of bit data by a tag transmitting apparatus, the method comprising:
converting 2 bits of the plurality of bit data into one symbol using phase information and orthogonal information; generating a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol; and transmitting the sub-carrier signal to a reader, wherein the method further comprises adding a dummy bit to effective data of the plurality of bit data when a bit number of the effective data is odd. |
