    • The application proposes an apparatus and a method for maximazing decoding performance by performing the soft decision decoding utilizing the inverse fast Hadamard transform (IFHT) even for block codes where the generator matrix does not include a basis of a Walsh code. In the apparatus, symbol position information for relocating each reception symbol is determined utilizing the block code generator matrix information having k rows and n columns and an IFHT size information for performing an IFHT for the reception symbols, each reception symbol is relocated as an input of an IFHT unit according to the determined symbol position information, the relocated symbols are input and the IFHT is performed for the symbols; and a codeword of the block code, which has a maximum correlation value from among result values obtained by performing the IFHT, is output as a decoding signal.
    • 该申请提出了几乎Hadamard变换的装置和用于通过执行软判决解码利用即使对于块码,其中该生成矩阵不包括的沃尔什码的基础的倒数(IFHT)maximazing解码性能的方法。 在重定位的每个接收符号的装置中,符号位置信息确定的开采利用具有用于在IFHT执行对接收码元k行和n列和IFHT尺寸信息块代码生成器矩阵的信息,每个接收符号被重新定位,以输入 到IFHT单元gemäß到确定性开采符号的位置信息,重新定位的符号被输入和IFHT执行用于符号; 和块代码,从通过执行IFHT获得的结果值中具有最大相关值的码字,是作为解码信号输出。
