    • A data relay method and a system for the same are provided to obtain a relatively big code gain as a source station, a relay station, and a destination station identically use convolutional turbo codes, not cyclic convolutional codes, in relaying data through a relay network. A data relay system(200) comprises the first puncturing unit(210), the second puncturing unit(220) and a data restoration unit(230). The first puncturing unit(210) codes data into a turbo codeword using convolutional turbo codes, primarily punctures the turbo codeword, and transmits the primarily punctured codeword to a relay station and a destination station from a source station. The second puncturing unit(220) decodes the primarily punctured codeword, secondarily punctures the decoded codeword, and transmits the secondarily punctured codeword to the destination station from the relay station. The data restoration unit(230) combines the turbo codewords, respectively received to the destination station from the source station and the relay station, into a turbo codeword, decodes the combined codeword, and restores the data.
    • 提供数据中继方法及其系统,以获得作为源站,中继站和目的站的相对较大的代码增益,在通过中继网络中继数据时,相同地使用卷积turbo码而不是循环卷积码 。 数据中继系统(200)包括第一穿孔单元(210),第二穿孔单元(220)和数据恢复单元(230)。 第一穿孔单元(210)使用卷积turbo码将数据编码成turbo码字,主要对所述turbo码字进行穿孔,并且将来自源站的主要穿孔码字发送到中继站和目的地站。 第二删截单元(220)对主要被穿孔的码字进行解码,二次对解码的码字进行穿孔,并从中继站向接收站发送二次删余的码字。 数据恢复单元(230)将分别从源站和中继站接收的目的地站的turbo码字组合成turbo码字,解码组合码字,并恢复数据。

    • A method and an apparatus for receiving data in a communication system are provided to prevent deterioration of the system by detecting data by tracking an RLS(Recursive Least Square) algorithm channel and performing a sphere-decoding. An apparatus for receiving data in a communication system includes a plurality of feedforward filters(211,213,215), a plurality of decoders(221,223,225), a pair of feedback filters(231,233), a pair of adders(241,243), and a coupler(250). The feedforward filters(211,213,215) cancel interference signals included in each component of inputted signals. The feedforward filters(211,213,215) and the feedback filters(231,233) perform an RLS algorithm. The decoders(221,223,225) decode signals inputted in a sphere-decoding method. The couplers(250) decide the weight of the feedforward filters(211,213,215) and the feedback filters(231,233).
    • 提供一种用于在通信系统中接收数据的方法和装置,以通过通过跟踪RLS(递归最小二乘法)算法信道并执行球解码来检测数据来防止系统的恶化。 一种用于在通信系统中接收数据的装置包括多个前馈滤波器(211,213,215),多个解码器(221,223,225),一对反馈滤波器(231,233),一对加法器(241,243)和耦合器(250) 。 前馈滤波器(211,213,215)消除输入信号的每个分量中包括的干扰信号。 前馈滤波器(211,213,215)和反馈滤波器(231,233)执行RLS算法。 解码器(221,223,225)解码以球体解码方法输入的信号。 耦合器(250)决定前馈滤波器(211,213,215)和反馈滤波器(231,233)的权重。
