基于频域的正交频分复用复基带信号的构造方法,以LTE(long term evolution)系统技术规范为基础,分析给出LTE系统正交频分复用复基带信号的构造方法,并给出低复杂度正交频分复用复基带信号的工程生成方法,验证基于频域的正交频分复用复基带信号构造方法的正确性,最后基于Matlab、WinIQSim、射频信号源及频谱分析仪组成的实验环境证明所阐述构造方法的正确性。
Through the illustration of frequency domain of orthogonal frequency division multiplexing system,the construction method of complex baseband signal for long term evolution(LTE)orthogonal frequency division multiplexing system based on LTE standard is analyzed and proposed to corroborate the proposed method,and a lower complexity engineering implementation method of complex baseband signal for orthogonal frequency division multiplexing system is also presented.An experimental environment based on Matlab,WinIQSim and radio frequency signal source is constructed to verify that the proposed method is correct.
