说明：  作为一个有吸引力的技术， 减轻多径干扰的正交频 分复用（OFDM）已经被广泛应用 在各种广播系统，诸如数字 视频广播（DVB）系统。尽管它的竞争力 属性，OFDM信号的特点是非常高的 峰值对平均功率比（PAPR）的水平。
( As an attractive technique in mitigating the multipath interference, Orthogonal Frequency Division Multiplexing (OFDM) has been widely applied in various broadcasting systems such as, the Digital Video Broadcasting (DVB) systems. Despite its competitive attributes, OFDM signals are characterized by very high Peak-to-Average Power Ratio (PAPR) levels.)
