用Multisim产生OFDM信号

摘要

For researching characteristics of OFDM signal, a digital-to-OFDM signal converter consisted of 4-frenquency & 4-phase signal generator, 8 2-to-1 analog switch and 8-input adder was made with MultiSIM. The waveform in the time domain of OFDM can be observed conveniently by oscilloscope.%为了研究OFDM信号的特性,使用Multisim制作了一个由四频四相信号发生器、八个二选一模拟开关和八输入加法器组成的Digital-OFDM信号变换器,用示波器可以方便地观察OFDM时域信号的波形.
