本文提出了综合非线性衰落信道下差分检测DQPSK/OFDM误码率(BER)的简单级数公式。该方法旨在推导存在非线性失真和符号间干扰（ISI）的情况下的理论误码率，这是评估 OFDM 信号综合性能的重要因素。由于所提出的公式由简单的级数形式表达式组成，因此可以避免耗时的模拟。在输入回退（IBO）和多径延迟等各种系统参数下，与计算机仿真结果的一致性证实了该方法的有效性。
This paper proposes a simple series form formula of the bit error rate (BER) for DQPSK/OFDM with differential detection under comprehensive nonlinear fading channels. The proposed approach aims to derive the theoretical BER in the presence of both the nonlinear distortion and the inter-symbol interference (ISI) which are the essential factors in evaluating the comprehensive performance of OFDM signals. Since the proposed formula is composed of the simple series form expression, the time-consuming simulations could be avoided. The validity of the proposed approach is confirmed by the agreement with the computer simulation results under various kinds of system parameters such as the input-backoff (IBO) and the multipath delay.
