摘要

本文研究了具有不同子信道数的非线性失真正交频分复用(OFDM)信号的误差概率行为。具体来说，我们表明，对于存在非线性的OFDM系统，增加子信道的数量并不一定会导致误码率的降低。我们还证明了非线性失真OFDM信号的误差概率的行为与信号的互调失真(IMD)的性质有关。

On the error probability performance of non-linearly distorted OFDM signals

In this paper, we examine the error probability behavior on non-linearly distorted orthogonal frequency division multiplexing (OFDM) signals with different numbers of subchannels. Specifically, we show that for OFDM systems in the presence of non-linearities increasing the number of subchannels does not necessarily result in degradation of the error rate. We also show that the behavior of the error probability of non-linearly distorted OFDM signals is related to the properties of the intermodulation distortion (IMD) of such signals.
