首发时间:2006-07-11
摘要:SOQPSK(Shaped Offset Quadrature Phase-Shift Keying)体制是近年来在卫星通信领域快速兴起的一种新的调制体制。文中分析评介了这种体制的发展历史、技术原理、体制性能。最后介绍了一种新的SOQPSK,并对其功率谱密度(PSD)进行了仿真。结果表明这种改进的SOQPSK功率谱密度的性能优于SOQPSK。

A Developed SOQPSK Modulation
Abstract:SOQPSK System is a new modulation system that is rapidly risen on the domain of SATCOM .In this paper ,we analyze and review the development history ,technical principle and performance of this modulation system. Finally, we introduce a new kind of SOQPSK, whose power spectral density (PSD) is simulated. The results demonstrate that the PSD performance of this developed SOQPSK is more excellent than SOQPSK.
Keywords: Shaped Offset Quadrature Phase-Shift Keying developed SOQPSK power spectral density
