    • The present invention relates a symbol generation apparatus for multiple antennas having low receiving complexity and having flexibility with respect to an increase in the number of antennas. The symbol generation apparatus includes a plurality of space-time channel encoders respectively corresponding to a plurality of channels, and an inverse fast Fourier transformer group. The respective space-time channel encoders receive a digital-modulated symbol group from the corresponding channel, perform a space-time encoding operation with respect to a plurality of space areas and at least one time area, shift phases by using a plurality of phase values, and generate a plurality of phase-shifted space-time codewords. The inverse fast Fourier transformer group performs an inverse fast Fourier transform operation by using the plurality of phase-shifted space-time codewords in a plurality of subcarriers respectively corresponding to the plurality of channels, and generates a plurality of inverse fast Fourier transformed signals.
    • 本发明涉及一种具有低接收复杂度的多个天线的符号产生装置,并且相对于天线数量的增加具有灵活性。 符号生成装置包括分别对应于多个信道的多个时空信道编码器和快速傅立叶逆变换组。 相应的时空通道编码器从对应的通道接收数字调制符号组,对多个空间区域和至少一个时间区域执行空时编码操作,通过使用多个相位值 并且生成多个相移时空码字。 逆快速傅里叶变换组通过使用分别对应于多个通道的多个子载波中的多个相移时空码字执行快速傅立叶逆变换,并产生多个快速傅里叶逆变换信号。
