摘要
Abstract
Small aperture antenna is limited by some disadvantages such as adjacent sallite inteference and TDMA frame efficiency,which affects the extension and application of the small aperture satellite communication earth station.The burst structure design is the key to improve TDMA frame efficiency.Several DVB-RCS commercial systems are analyzed on basis of the reaserch on DVB-RCS standards.A method is proposed which integratedly consides frame length,carrier rate,time slot number and proper burst structure design at various carrier rates on basis of the analysis of TDMA burst structure.This method can improve MF-TDMD frame efficiency.The spread spectrum solution is proposed for adjacent satellite inteference of small aperture antenna,and its effectiveness is verified through calculation and simulation.关键词
