摘要：

In non-cooperative communication scenarios, coherent demodulation of Continuous Phase Modulation (CPM) signals requires precise estimation of CPM modulation parameters. A new data-aided modulation index and shaping pulse joint estimation algorithm is proposed for CPM signals. The differential phase between symbols is used to eliminate signal phase memories, and Least-Square method is used for parameters estimations. Theoretical analysis and numerical simulations show that it is unbiased. The estimating error is converged to zero at 1/N where N is the length of observation data. The algorithm is applicable to both full and partial response CPM modulations and presents good anti-noise performance.
