Power and spectrally efficient M-ARY QAM schemes for future mobile satellite communications [PDF]

An effective method to compensate nonlinear phase distortion caused by the mobile amplifier is proposed. As a first step towards the future use of spectrally efficient modulation schemes for mobile satellite applications, we have investigated effects of ...

Constellation design of 32-QAM by scaling two square 16-QAMs with dual-level coding

ICT Express
In this paper, we propose a 32-quadrature amplitude modulation (QAM) constellation to achieve high spectral efficiency, along with dual-level coding (DLC) and successive cancellation decoding (SCD).
