    摘要: Provided is an apparatus and method for transmitting packet data in a WSN. The apparatus for transmitting packet data in a WSN includes: a serial-to-parallel converter to parallel-convert information and output the converted information to two channel paths; a Walsh code pair generation unit to select an arbitrary Walsh code pair, mix the selected Walsh code pair with a pseudo noise (PN) code, and output one Walsh code to one channel path and the other Walsh code to the other channel path; a first mixer to mix the signals inputted to two channel paths, and generate a spread symbol for each path; a delay to delay the other channel path signal by a predetermined time; and a transmission unit to convert one channel path signal and the other channel path signal delayed by the delay into transmission frequency band signals, and transmit the converted signals as wireless signals.

    摘要: Provided are a Radio Frequency Identification (RFID) tag and apparatus and method for locating a RFID tag without comparing arrival times of blink signals transmitted from the RFID tag in order to quickly trace a location of the RFID tag. The RFID tag includes a tag ID generator configured to generate a tag ID of the RFID tag, a blink generator configured to generate a plurality of sub-blink signals that form the blink signal, a sub-blink ID generator configured to generate sub-blink IDs for the generated sub-blink signals, a sub-blink ID inserter configured to insert the generated sub-blink IDs into the sub-blink signals, and a transmitter configured to transmit the blink signal having the tag ID and the sub-blink IDs.
