摘要

Aimed at power-limited and nonlinear channels of satellite communications, a novel PSWF-based multidimensional constellation modulation is proposed. This modulation maps initial data onto points in a multidimensional constellation, where multiple orthogonal PSWF pulses with high energy concentration are used to convey these constellation points. To maximize the minimum Euclidean distance, an efficient constellation design is presented. Simulation and measurement results show the modulation is 4 dB better than 16-APSK and 16-QAM in SNR for SER = 10(-5) and has outstanding advantages in the SER performance and resilience against nonlinear distortions for the same spectral efficiency and data rate as other modulations currently employed.
