The device includes: a blocking unit (106) which adds a bit indicating an error detection result in a CRC unit (105) to control data (a bit string) so as to constitute an encoded block and outputs the encoded block to an encoding unit (107); and the encoding unit (107) which corrects and encodes the encoded block. The blocking unit (106) forms an encoded block by a bit string of control data and a probability deviation existence bit added to the tail of the bit string.

摘要： Provided is a wireless transmitter capable of accurately specifying the number of multiplexed streams and correctly decoding the data signals when a preamble sequence transmitted from any antenna of a wireless transmitter is detected. In this device, a multiplex count determination unit (101) determines the number of streams used by the device itself from the same number of candidates as the number of spatially multiplexed streams. A sequence group generator (104) forms a plurality of preamble sequences into the same number of groups as the number of candidates, which is the number of streams. A sequence group selector (105) selects the group matching the number of streams determined by the multiplex count determination unit (101) from a plurality of groups. A preamble generator (106) selects the same number of preamble sequences as the number of streams in the group selected by the sequence group selector (105) and generates the preamble sequence used by the device itself.

摘要： A radio transmitting apparatus wherein even if a preamble sequence transmitted via any one of the antennas of the radio transmitting apparatus is detected, the order of the space diversity can be determined with reliability and data signals can be normally decoded. In this apparatus, a deciding unit (101) decides preamble sequences the number of which is equal to the order of the space diversity and further decides transmission block intervals the number of which is equal to or greater than the order of the space diversity. An allocating unit (102) sequentially allocates the preamble sequences, the number of which is equal to the order of the space diversity, to the respective antennas, the number of which is equal to the order of the space diversity, within the respective transmission block intervals. The allocating unit (102) allocates different ones of the preamble sequences to the respective antennas at the respective same transmission timings that are within the respective transmission block intervals.
