    • A quantum key delivery method is a method for estimating original transmission data from reception data having probability information. For example, parity check matrix generation sections (10, 30) generate the same parity check matrixes and a syndrome generation section (14) notifies error correction information generated according to the parity check matrix and the transmission data to a communication device of the reception side via a public communication path. A syndrome decoding section (33) estimates the transmission data according to the error correction information and the reception data having the probability information. Furthermore, until the errors of the reception data are corrected completely, an error correction process is repeatedly executed by increasing the number of rows of the parity check matrix under a predetermined constraint condition.

    • A subframe data transmission device for a mobile communication system. A bit generator generates specific bits having a predetermined value. A bit inserter segments a received data bit stream into at least two subframes, and inserts the generated specific bits at locations where an error probability is higher in the respective subframes. A turbo coder codes the subframe data comprised of the data bit stream and the specific bits. The subframe is equal in size to an ARQ (Automatic Repeat Request) block, and the specific bits are inserted at a rear portion of the subframe. The bit inserter includes a delay for delaying the received data bit stream by the number of the specific bits to be inserted; and a selector for connecting, upon completion of receiving data bits for the subframe, the received data bits to the delay and applying an output of the bit generator to the turbo coder; and applying, when the specific bits are inserted, an output of the delay to the turbo coder.
    • 一种用于移动通信系统的子帧数据传输设备。 位发生器产生具有预定值的特定位。 比特插入器将接收到的数据比特流分割成至少两个子帧,并将生成的特定比特插入到各个子帧中错误概率较高的位置处。 Turbo编码器对由数据比特流和特定比特组成的子帧数据进行编码。 子帧的大小与ARQ(自动重复请求)块的大小相等,并且特定比特被插入子帧的后部。 比特插入器包括用于将接收到的数据比特流延迟要插入的特定比特的数量的延迟; 以及选择器,用于在完成接收子帧的数据比特后,将接收到的数据比特连接到延迟,并将比特发生器的输出应用到turbo编码器; 并且当插入特定比特时,将延迟的输出应用于turbo编码器。

    • PURPOSE: An apparatus and method for detecting a transmission rate of a turbo decoder is provided to adjust the number of turbo-decoding repetition in case of detecting a transmission speed of turbo-coded data. CONSTITUTION: A decoder(101) variably decodes a received signal according to a selected transmission speed. A CRC(Cyclic Redundancy Code) detector(109) extracts CRC data from the output of the decoder(101). A decoding state measurer(111) determines the number of repetition for executing the decoding from the output data of the decoder(101). A controller(113) determines the number of decoded times of the decoder(101) as an initial minimum value, changes the number of decoding according to the output of the decoding state measurer(111), checks the CRC data, judges a speed of the transmitted data, and determines a kind of the decoded data. A speed value determiner(115) determines a decoding speed value of the decoder(101) by the control of the controller(113).
