摘要
编码正交频分复用调制方式是较为完备的移动接收和传输技术,可大大降低每个子载波内的符号间干扰,节省了用于均衡的系统开销。正交频分复用(OFDM)是一种多载波传输方式,当每路载波的带宽小于Δf时,可有效地抑制由频率选择性衰落而造成的码间干扰。
The modulation way of COFDM is a mature receiving and transimitting technique , which can lower the interference of symbol in each carrier and economize the system expense used for balance . OFDM is a transmission way of carriers , when bandwidth of each carriers is less then Δf, it can effectively repress the interference between codes caused by the decline of frequency selectivity .
