论文摘要
这项研究撤销了能够直接生成单层（SSB）频谱的连续相调制（CPM）的性能。根据调制指数，脉冲长度和脉冲宽度对此信号进行分析，所有这些信号都会影响误差概率，带宽，SSB属性和接收器复杂性。误差概率性能基于最小欧几里得距离的近似值。提出了该特定SSB调制的数值功率谱密度计算，以调制指数表示。在设计调制方案方面的合理权衡是使用多目标优化提出的，以确保位错误率（BER），频谱效率和复杂性的显着提高，而不会失去成为SSB信号的特性。性能比较是通过已知的CPM方案进行的，例如高斯最小移动键（GMSK）和基于余弦的CPM（RC）
This study revokes the performance of continuous phase modulation (CPM) able to generate a single-sideband (SSB) spectrum directly. This signal is analyzed in terms of modulation indices, pulse lengths, and pulse widths, all of which affect error probability, bandwidth, SSB property, and receiver complexity. The error probability performance is based on an approximation of the minimum Euclidean distance. A numerical power spectral density calculation for this particular SSB modulation in terms of modulation index is presented. Reasonable tradeoffs in designing modulation schemes have been proposed using multi-objective optimization to ensure sizable improvements in bit error rate (BER), spectral efficiencies, and complexity without losing the property of being a SSB signal. Performance comparisons are made with known CPM schemes, e.g., Gaussian Minimum Shift Keying (GMSK) and Raised Cosine based CPM (RC)
