首先将复数符号通过取实和取虚分成实部符号虚部符号，实部和虚部符号再分别通过 OQAM 调制，使二者错开一个相位，并保证二者保持正交，然后分别经滤波器组 G ( n )和 G ( n − N2)来消除多径信道影响产生的 ISI，经加法器将信号相加形成发射信号 s ( t )，过多径信道、高斯信道后，接收信号 r ( t )分别经滤波器组 G ( n− 1)和 G ( N 2− n)消除发射机滤波器组的影响，再分别通过N 点 FFT 变换把接收信号变为频率形式，然后通过 OQAM 解调使得错开的实、虚部相位回到相同的相位，保持实、虚部信号同步，最后收到的信号和 CE 得到的信道冲激响应系数一起进入迫零(Zero Forcing, ZF)均衡器解调出实、虚部符号，经取实、取虚后，最后合成复数形成解调数据符号
