本文研究了M-PSK和M-QAM调制的正交频分复用（OFDM）信号在加性白色高斯噪声（AWGN）信道中的传输。分析了载波频偏和载波相位噪声对系统误码率的影响。它示出，对于一个给定的BER退化，允许OFDM的载波发生器的频率偏移和线宽的值的数量级小于进行相同的比特率的单载波系统。>
In this contribution the transmission of M-PSK and M-QAM modulated orthogonal frequency division multiplexed (OFDM) signals over an additive white Gaussian noise (AWGN) channel is considered. The degradation of the bit error rate (BER), caused by the presence of carrier frequency offset and carrier phase noise is analytically evaluated. It is shown that for a given BER degradation, the values of the frequency offset and the linewidth of the carrier generator that are allowed for OFDM are orders of magnitude smaller than for single carrier systems carrying the same bit rate. >
