摘要： D-dimensional vectors that each have D real-valued symbols as elements are converted into D-dimensional rotated vectors that each have D real symbols as elements. The conversion is performed by multiplying each of the D-dimensional vectors by a D×D orthogonal matrix. A complex symbol sequence including N C = N S /2 complex symbols is generated from N S real symbols. The complex symbol sequence is generated such that the distance between any two of the D real symbols of each of the D-dimensional rotated vectors is N C /D complex symbols or N C /D-l complex symbols, or such that the distance between any two of the D real symbols of each of the D-dimensional rotated vectors, except for part of the D-dimensional rotated vectors, is N C /D complex symbols or N C /D-l complex symbols.
摘要翻译：分别具有D个实值符号作为元素的D维矢量被转换为D个旋转矢量，每个D维旋转矢量具有D个实数符号作为元素。通过将每个D维矢量乘以D×D正交矩阵来执行该转换。从NS个实符号生成包括NC = NS / 2个复符号的复符号序列。生成复数符号序列，使得每个D维旋转向量中的任何两个D实符号之间的距离是NC / D复数符号或NC / Dl复数符号，或者使得任何两个D维实数符号之间的距离 D维旋转向量中的每一个的除D维旋转向量之外的D个实符号是NC / D复数符号或NC / D1复数符号。

摘要： The present invention relates to bit interleaving and de-interleaving of quasi-cyclic low-density parity-check (QC-LDPC) codes for a communication system with spatial multiplexing over a plurality of transmit antennas and discloses a bit interleaver and a corresponding method that achieves optimum diversity and allows for a particularly efficient hardware implementation due to its high degree of parallelism. To this end, a permutation for mapping the bits of the QC-LDPC codeword to a sequence of constellation words is constructed such that (i) each constellation word is made up of bits from Bt/2 different cyclic blocks of the codeword, Bt being the number of bits of the constellation word, (ii) each pair of constellation word bits that have the same robustness is made up of bits from the same cyclic block, and (iii) constellation words for different antennas are made up of bits from different cyclic blocks.
