In three standards, ATSC is the single carriertransmission system, it is easy to support the fixed receiving, its peak average value quite being small.
在三大标准中atsc为单载波传输系统，能较好支持固定接收，峰均值比较小。

Multi-carriertransmission technology-Orthogonal Frequency Division Multiplexing (OFDM), as the core technology of beyond 3g, has the characteristic of high data rate.
