中文摘要：
基于星座点和高 signal-to-noise 比率(SNR ) 的大数字的假设，格子星座的阶段噪音敏感被分析。在添加剂白人 Gaussian 噪音(AWGN ) 的标志错误率(重量的单位) 的上面的界限隧道从 pairwise 错误概率被导出。为小阶段噪音，阶段噪音隧道被转变到 AWGN 隧道。在维纳模型的帮助下，获得的上面的界限能被扩大分阶段执行噪音隧道。建议上面的界限能被用作表演标准在多维的格子星座分析阶段噪音的敏感。模拟结果显示出那，一样使正常化光谱效率，更高维的格子星座是比在阶段噪音的更低的更敏感的隧道。它也与星座的一样的尺寸被看那，更大使正常化光谱效率在阶段噪音意味着更多的表演损失隧道。
英文摘要：
Based on the assumption of large number of constellation points and high signal-to-noise ratio （SNR）, phase noise sensitivity of lattice constellation is analyzed. The upper bound of symbol error rate （SER） in additive white Gaussian noise （AWGN） channel is derived from pairwise error probability. For small phase noise, phase noise channel is transformed to AWGN channel. With the aid of Wiener model, the obtained upper bound can be extended to phase noise channel. The proposed upper bound can be used as performance criterion to analyze the sensitivity of phase noise in multi-dimensional lattice constellation. Simulation results show that with the same normalized spectral efficiency, higher dimensional lattice constellations are more sensitive than lower ones in phase noise channel. It is also shown that with the same dimension of constellation, larger normalized spectral efficiency means more performance loss in phase noise channel.
