    摘要: The invention provides an RFID tag for storing large scale multimedia contents data readable only when it is authenticated, remote authentication for accessing the multimedia contents data stored in the RFID tag, and a wireless communication system and method for transmitting/receiving the multimedia contents on a radio frequency through the authentication. Specifically, the tag includes: a wireless communication unit transmitting/receiving the first and second request signals and the first and second data signals; a first memory device storing first data for the first data signal; a second memory device storing second data for the second data signal; a tag control unit which generates and transmits the first data signal based on the first data in response to the first request signal from the reader device, or generates and transmits the second data signal based on the second data in response to the second request signal from the reader device; and an authentication unit selectively prohibiting the tag control unit from accessing the second memory device depending on authentication information contained in the second request signal.

    摘要: A block interleaving apparatus for block interleaving M-bit input streams to be transferred with a modulus k using a mixed radix system in a multi-band orthogonal frequency division multiplexing communication system, including an array processor having an array including M cells in which the number of columns is k and the number of rows is M/k. The array processor inputs the input streams from the bottom-right cell up to the top-left last cell in the horizontal direction, and, after the first bit of the input streams reaches the last cell, generates interleaved output streams by changing the output of the array processor from horizontal direction to vertical direction.
