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 the 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).

单边带连续相位调制的性能与频谱特性

该研究取消了能够直接生成单边带 (SSB) 频谱的连续相位调制 (CPM) 的性能。该信号根据调制指数、脉冲长度和脉冲宽度进行分析,所有这些都会影响错误概率、带宽、SSB 属性和接收器复杂性。错误概率性能基于最小欧几里德距离的近似值。提出了在调制指数方面针对该特定 SSB 调制的数值功率谱密度计算。已经提出了使用多目标优化设计调制方案的合理折衷方案,以确保在不失去作为 SSB 信号的特性的情况下大幅提高误码率 (BER)、频谱效率和复杂性。与已知的 CPM 方案进行性能比较,例如,
