Modulation analysis in wireless co-time co-frequency full duplex

In this paper, we analyze the signal modulation impact on wireless co-time co-frequency full duplex system. The self-interference cancellation ratio is calculated mathematically in different modulation types, including Quadrature Amplitude Modulation (QAM) and Continue Phase Modulation (CPM). Simulation results matches well with the analytical results, and the self-interference cancellation ratio in CPM is better than that in QAM.
