摘要

在卫星物联网通信中，导频资源和存储资源均受到一定限制，传统同步方案及其硬件实现面临着很大的挑战。针对这一问题，提出了一种基于双相关算子的极简同步方案，包括频相解耦合估计和分块相关数据补偿两部分。其中，频相解耦合估计部分提供了一个对莱斯衰落鲁棒的自相关频偏估计器和一个抗频偏能力强的低复杂度相偏估计器；分块相关数据补偿部分只需使用基于互相关算子的少量数据补偿值便可以显著降低残留频偏的影响。仿真结果表明，在最大仅5%的导频开销下，所提极简同步方案能够实现频偏对相偏的解耦合，同时比传统同步方案减少98%的存储空间占用并在低信噪比下获得接近的误码性能，对未来卫星物联网通信系统的工程实现有着一定现实意义。

Abstract

In satellite Internet of things (IoT) communications

both pilot and storage resources are limited such that conventional synchronization scheme and its hardware implementation have faced great challenges. To address this issue

a minimal synchronization scheme was proposed based on double correlation operators

including an auto-correlation based frequency-phase decoupled estimation and a cross-correlation based crorelation blockwise data compensation. In specific

an auto-correlation frequency offset estimator robust was provided by the former to the Rice fading and a low-complexity phase offset estimator with a strong ability of anti-frequency offset. A small amount of cross-correlation based data compensation values were used by the latter to greatly lower the impact of residual frequency offset. Simulation results show that with a maximum pilot overhead of only five percents

the proposed minimal synchronization scheme can implement the frequency-to-phase decoupling

and can reduce storage space occupation by 98% and achieve near error performance at the low signal-to-noise ratio (SNR) compared with the conventional synchronization scheme

which has certain practical significance for engineering implementation of future satellite IoT communication systems.
