Performance vs. Spectral Properties For Single-Sideband Continuous Phase Modulation

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)
Comment: - We added a new optimization method to take into consideration the complexity. - We added a new comparison between new SSB-FSK schemes and the CPM modulations (RC, GMSK). - We presented a new SSB-FSK scheme with some good synchronization advantages. - We fixed some typo mistakes. - We updated the overall quality of the paper
