  • Patent number: 8464139
    Abstract: A receiving device in a communication system that separates one frame of information bits into plural blocks, performs turbo encoding of the information bits of each block and transmits the result, and decodes the encoded information bits, where the receiving device includes plural decoders number of which is less than the number of blocks per frame. Each decoder performs a decoding process on encoded information bits of each block that have been expressed by likelihood, when a condition for stopping decoding is met, executes the decoding process of encoded information bits of another block for which decoding has not yet been performed. When the condition for stopping decoding has been met for all blocks before the number of times decoding has been performed for each decoder reaches a preset maximum number of repetitions, the decoding results of all the blocks are serially combined, an error detection process is executed.

  • Patent number: 8458579
    Abstract: A method in a communication system, where a systematic code obtained by systematic encoding of information bits having dummy bits inserted and by deletion of the dummy bits from results of the systematic encoding is transmitted. On a receiving side, the deleted dummy bits are inserted into the received systematic code and then decoded. The method includes: deciding a size of dummy bits for insertion into information bits; segmenting the information bits into a number of code blocks when a bit size of the information bits is greater than a stipulated size; inserting dummy bits into each block of the segmented information bits in conformity with a dummy bit insertion pattern; performing systematic encoding of each block of the information bits into which the dummy bits are inserted, and deleting the dummy bits from the results of the systematic encoding to generate a systematic code.

  • Patent number: 8451805
    Abstract: A radio wave detecting apparatus that can perform carrier sense of radio waves subjected to spread spectrum with a simple configuration, in which a spread code is multiplied by an information signal, the band is spread, and a spread information signal is generated. A beacon signal in a predetermined band is synthesized with the spread information signal, and a synthesized signal is transmitted as a radio wave. Furthermore, only a signal component in a predetermined band is extracted from a received radio wave, so that a beacon signal is separated. The presence of a radio wave is detected based on the receiving power of the separated beacon signal. If the presence of the radio wave is detected, the transmission of the radio wave is stopped.
