高信噪比下维纳相位噪声信道的研究

On Wiener Phase Noise Channels at High Signal-to-Noise Ratio

Hassan Ghozlan, Gerhard Kramer

摘要:

考虑波形信道,其中发送的信号被维纳相位噪声和加性高斯白噪声(AWGN)破坏。建立了一种考虑滤波对相位噪声影响的离散时间信道模型。该模型是基于一个多样本接收机,在高信噪比(SNR),实现了一个速率,如果每个符号的样本数与SNR的平方根的增长与SNR的几何增长。此外,在这种情况下,前对数因子至少为1/2。

英文摘要:

Consider a waveform channel where the transmitted signal is corrupted by Wiener phase noise and additive white Gaussian noise (AWGN). A discrete-time channel model that takes into account the effect of filtering on the phase noise is developed. The model is based on a multi-sample receiver which, at high Signal-to-Noise Ratio (SNR), achieves a rate that grows logarithmically with the SNR if the number of samples per symbol grows with the square-root of the SNR. Moreover, the pre-log factor is at least 1/2 in this case.
