| 摘 要： | 提出了一种适用于任意天线数和子载波数MIMO-OFDM系统的高速全分集（球）空频码的新型设计方法。在融合球码和空时码的基础上,该码具有差分几何结构,其速率取决于格子维数和最小距离,通过格子旋转,球空频码可获得全分集。仿真结果表明在高速时编码性能较为理想,且译码复杂度适度。

| Abstract: | In this paper, a new design mothod for high rate, full-diversity spherical space frequency codes suitable for arbitray numbers of antennas and subcarriers for MIMOOFDM systems is proposed. By combining spherical codes with space-time codes, this scheme is of differential geometric construction, and its code rate is determined by the choice of underlying lattice and the designed minimal distance, and through the rotation of lattice, the spherical space frequency code could achieve full diversity. The simulat... |
