摘要

介绍了正交频域调制-连续相位调制(OFDM-CPM)在多径标准大学过渡信道中的应用。结果表明，除OdB的峰值平均功率比(PAPR)和功率效率外，无编码OFDM-CPM还利用了多径信道的频率分集。考虑到输入功率回退(IBO)， OFDM- cpm在高比特能量噪声密度比(Eb/N0)下表现优于OFDM。然而，在低信噪比(SNR)下，OFDM-CPM相位解调器接收机受到阈值效应的影响。SUI通道的模拟结果证实了这一分析。

OFDM-CPM BER Performance in SUI Multipath Channels

This paper presents the application of Orthogonal frequency domain modulation-Continuous Phase Modulation (OFDM-CPM) in multipath Standard University Interim (SUI) channels. It is shown that, in addition to OdB Peak to Average Power Ratio (PAPR) and power efficiency, uncoded OFDM-CPM exploits the frequency diversity of multipath channel. Taking into account the Input Power Backoff (IBO), OFDM-CPM is shown to outperform OFDM at high bit energy-to-noise density ratios (Eb/N0). However, at low Signal to Noise Ratio (SNR), the OFDM-CPM phase demodulator receiver suffers from a threshold effect. Simulation results in SUI channels confirm the analysis.
