| 摘 要： | 提出了基于坐标交叉正交设计的空时分组码(CLOD STBCs)。与复数正交设计空时分组码(COD STBCs)相比，具有相同的译码复杂性，但速率为1的CIOD STBCs对2～4个发射天线都存在，而COD STBCs仅仅对2个发射天线存在；速率为3／4的CIOD STBCs对5～8个发射天线都存在，而广义COD(GCOD)STBCs仅仅对3、4个发射天线存在．最后分别对它们进行了仿真。

| Abstract: | Coordinate interleaved orthogonal design (IOD) space-time block codes (STBCs) were put forward. A channel model was formulated, then complex orthogonal design space-time block codes were explored, and coordinate interleaved orthogonal design space-time block codes were researched. The CIOD STBCs have the same low decoding complexity as the COD STBCs. But rate 1 CIOD STBCs exist for two, three and four transmit antennas while COD STBCs exists only for two transmit antennas. And rate 3/4 CIOD STBCs exist for five, six, seven and eight transmit antennas while COD STBCs exist only for three and four transmit antennas. At last, simulations for the COD STBCs and the CIOD STBCs were made (respectively). |
