    Abstract: A present technology relates to a transmission device, a transmission method, a reception device, a reception method, and a program that can improve reception performance of a frame to which a preamble is added. A transmission device of one aspect of the present technology generates a preamble including a sequence [d d . . . d ?d] having iteration of a sequence d that is one of sequences a and b that are Golay complementary sequences, followed by an inverted sequence of the sequence d, and including a signal sequence in which a maximum value of an absolute value of a side lobe level of cross correlation between a sequence [d d ?d] and a sequence [d ?d] is 25 or less. The generated preamble is added to data to be transmitted in units of frames. The present technology can be applied to a device that transmits and receives data via a wireless transmission path.

  • Patent number: 8649093
    Abstract: As the polarizing fiber of the present invention, the cross sectional form perpendicular to the longitudinal direction has a sea-island structure, and the cross sectional form is continuously made up in the longitudinal direction. A resin (sea component) that constitutes the sea region of the sea-island structure comprises a dichroic dye, and a resin (island component) that constitutes the island regions of the sea-island structure is a transparent resin. The polarizing fiber of the present invention may be used as a forming material of a polarizer, for example. By using the above polarizing fiber, a polarizer wherein unevenness of the transmittance is small and cracks are less generated may be formed.
