OFDM具有很强的抗多径和抗频率选择性衰落的能力，并且可以传输高速数据，这里以DVB_T（2k模式）为例分析其加信道厚的信号频谱及信道对OFDM中频信号的影响。(The purpose of this programme is to provide Matlab code to simulate the basic processing involved in the generation and reception of an OFDM signal in a physical channel and to provide a description of each of the steps involved. For this purpose,we shall use, as an example, one of the proposed OFDM signals of the Digital Video Broadcasting (DVB) standard for the European terrestrial digital television (DTV) service.)
