摘要
Abstract
A timing recovery scheme is proposed for high-rate satellite data transmission. Compared with typical schemes,it has simple structure and doesn't depend on special hardware. The solution works at a fixed sampling clock. Timing-error detector is utilized to sort and screen data distributed in multiple branche,and timing information is recovered by parallel interpolation. It can synchronize a variety of band-width signals up to gigahertz. Hardware simulation results show the demodulation loss is no less than 1 dB. Digital receivers using such scheme can work on uniform platforms,which makes the ground resource distri-bution of satellites tracking,telemetry and command( TT&C) and communication systems more flexible.关键词
