    • PROBLEM TO BE SOLVED: To provide an improved method and transmitter circuit for transmitting data via multiple antennas.SOLUTION: The method of the invention comprises: modulating data to be transmitted into a plurality of modulated symbols; encoding each pair of modulated symbols from among the plurality of symbols in accordance with a transmission diversity scheme to result in a plurality of N by N matrices, with each N by N matrix corresponding to each pair of modulated symbols; generating a M by M code matrix comprised of the plurality of N by N matrices; orthogonally spreading the M by M code matrix to generate an output matrix; generating a plurality of row-permuted matrices by exchanging at least one pair of rows in the output matrix; and transmitting the symbols in the plurality of row-permuted matrices via a plurality of antennas by using a scheme such as a space time transmission diversity scheme.
    • 要解决的问题:提供一种用于经由多个天线发送数据的改进的方法和发射机电路。 解决方案:本发明的方法包括:将要发送的数据调制成多个调制符号; 根据传输分集方案从多个符号中的每一对调制符号编码以产生多个N乘N个矩阵,每个N乘N个矩阵对应于每对调制符号; 由多个N乘以N个矩阵生成由M个码矩阵组成的M码; 通过M代码矩阵正交地扩展M以产生输出矩阵; 通过在输出矩阵中交换至少一对行来产生多个行排列矩阵; 以及通过使用诸如空时传输分集方案的方案,经由多个天线发送多个行排列矩阵中的符号。 版权所有(C)2013,JPO&INPIT
