    • How to apply an Alamouti like space-time coding (or transmit diversity) to a Filter Bank Multicarrier (FBMC) transmission using Offset QAM (OQAM). In FBMC, due to the orthogonality in the real domain only, an intrinsic interference results thereof for the imaginary component. Simply adapting the Alamouti scheme to FBMC OQAM is not obvious since the intrinsic interference terms are not equivalent at each antenna since it depends on the surrounding symbols. The application proposes to use a precoding symbol chosen to cancel out (zero) the intrinsic interference individually for each antenna, ie a code rate of 1/2 (sending one data symbol requires two time units). A more elaborated embodiment proposes to choose the contiguous precoding symbols such that a virtual QAM Alamouti scheme is achieved, without rate loss.
    • 如何使用偏移QAM(OQAM)将Alamouti像空时编码(或发射分集)应用于滤波器组多载波(FBMC)传输。 在FBMC中,由于仅在真实域中的正交性,其对于虚部具有固有干扰。 简单地将Alamouti方案适应于FBMC OQAM并不明显,因为固有干扰项在每个天线上不相等,因为它取决于周围的符号。 该应用提出使用选择的预编码符号来消除(零)每个天线的固有干扰,即码率为1/2(发送一个数据符号需要两个时间单位)。 更详细的实施例提出选择连续的预编码符号,使得实现虚拟QAM Alamouti方案,而没有速率损失。
