本文研究了理想加性高斯白噪声信道和频率选择信道中恒包络正交频分复用（CE-OFDM）信号的最佳性能，并将其与基于鉴相器的传统CE-OFDM接收机的性能进行了比较。结果表明，该鉴相器仅在功率效率很低的情况下才能达到最佳性能。因此，在功率受限的情况下使用CE-OFDM方案可能需要其他类型的接收器，例如基于最优的接收器。
In this letter, we study the optimum performance of constant envelope orthogonal frequency division multiplexing (CE-OFDM) signals in both ideal additive white Gaussian noise channels and frequency-selective channels, and we compare it to the performance of conventional CE-OFDM receivers based on a phase detector. It is shown that the phase detector can achieve optimum performance, but only in scenarios where the power efficiency is very low. For this reason, the use of CE-OFDM schemes in power-constrained scenarios may demand other type of receivers, such as optimum-based receivers.
