    Abstract: Generating a channel state information (CSI) feedback report is provided. A set of reference signals is received (1502). A set of entries that are included in the CSI feedback report is computed (1504). Each entry has a most significant bit, and one or more remaining bits, where an order of each of the entries in the CSI feedback report are arranged based upon a bit level classification of the entries (1508). A value of the most significant bit of each of the entries is identified, and the entries, which have a most significant bit value corresponding to a higher bit value have the remaining bits arranged in a group that is positioned in the CSI feedback report prior to a group of tire remaining bits of the entries, which have a most significant bit value corresponding to a lower bit value (1510).

    Abstract: The present technology relates to an encoding device, an encoding method, a decoding device, a decoding method, a program, and a wireless communication system that enable efficient transmission of frames in accordance with the condition of the transmission path.An encoding device of one aspect of the present technology encodes and modulates transmission data stored in a payload, and encodes and modulates modulation/encoding information by predetermined schemes, the modulation/encoding information indicating at least one of the schemes of encoding and modulation for stored information stored in a header, and at least one of the schemes of encoding and modulation for the transmission data. The encoding device also encodes and modulates the stored information by schemes indicated by the modulation/encoding information, and transmits a frame formed by attaching the header to the payload, the header being formed with a first region and a second region, the first region storing the modulation/encoding information, the second region storing the stored information. The present technology can be applied to devices that perform wireless communication using a 60 GHz band, for example.

    Abstract: A method is provided for improving the acquisition of a data set transmitted repeatedly in a difficult environment, which is particularly appropriate to satellite radionavigation systems. The main characteristic of the method is to provide “contextual” aid relating to the transmitted data by indicating the nature and the possible updating of these data so that the receiver can accumulate the energy when the data are repeated in an identical manner. These aid data being short, it is possible to obtain good quality of reception and protection of this aid by virtue of its longer coding than that of the data.

    Abstract: Data communication, with improved error detection, of a signal having a plurality of data blocks, by: error checking a received data block in a first sequence using a first polynomial, beginning with a first predetermined initial error checking state, producing a first CSUM; error checking the received data block in a second sequence using a second polynomial, using the first CSUM as a second predetermined initial error checking state, producing a second CSUM; comparing the second CSUM to the first predetermined initial error checking state to detect errors in the data communication; and repeating the above steps for sequential data blocks of the data communication, wherein the first polynomial is an inverse of the second polynomial.

    Abstract: The writing address supply part 210 supplies writing addresses for writing the bits forming bit sequences corresponding to the header H contained in a frame to be transmitted or stored and bit sequences corresponding to the data D, into the operating memory 220. The reading address supply part 230 alternately supplies to the operating memory 220 a plurality of addresses for reading a plurality of continuous bits corresponding to the header H from the operating memory 220, and an address for reading 1 bit corresponding to the data D from the operating memory 220, and reads the bit sequence such that the bits forming the bit sequence corresponding to the header H are scattered and arranged within the bit sequence forming the data D, from the operating memory. In accordance with such an interleaving device, it is possible to individually randomize frames according to their constituent data, and it is possible to transmit the bits that make up such data in a format which is most suited for said data.
