Synthesis of Signals with a Low-Level of Out-of-Band Emission and Peak-to-Average Power Ratio
2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)(2018)
摘要
In this paper new pulse shapes of multicomponent signals are presented to improve spectral efficiency. We propose a solution to an optimization problem for obtaining optimal pulse shapes. The optimization problem is expressed by the restriction of out-of-band emission and the restriction of the peak-to-average power ratio (PAPR) magnitude. It was shown that using multicomponent signals with optimal pulse shapes allows to improve spectral efficiency.
