摘要

移动无线电通信系统的设计通常不考虑相对发射/接收动态。在本文中，我们将这种动态建模为矢量马尔可夫过程，并将测距和数字解调/检测作为递归绝对(非模2/spl pi/)相位估计的方面。符号间隔内的符号检测和相位跟踪由一组“匹配”随机非线性估计器和最大后验(MAP)决策算法完成。该方法适用于与低地球轨道(LEO)卫星或快速机动平台之间的精确着陆和通信。

Recursive Bayesian phase estimation in ranging and mobile communication

Mobile radio communication systems are generally designed without taking into account the relative emitter/receiver dynamics. In this paper we model this dynamics as a vector Markov process and formulate ranging and digital demodulation/detection as aspects of recursive absolute (not modulo 2/spl pi/) phase estimation. Symbol-by-symbol detection and phase tracking within symbol interval are performed by a bank of 'matched' stochastic nonlinear estimators and a maximum a posteriori (MAP) decision algorithm. The approach applies to precision landing and communication with low Earth orbit (LEO) satellites or between rapid maneuvering platforms.

期刊介绍： Journal of Signal Processing is an academic journal supervised by China Association for Science and Technology and sponsored by China Institute of Electronics. The journal is an academic journal that reflects the latest research results and technological progress in the field of signal processing and related disciplines. It covers academic papers and review articles on new theories, new ideas, and new technologies in the field of signal processing. The journal aims to provide a platform for academic exchanges for scientific researchers and engineering and technical personnel engaged in basic research and applied research in signal processing, thereby promoting the development of information science and technology. At present, the journal has been included in the three major domestic core journal databases "China Science Citation Database (CSCD), China Science and Technology Core Journals (CSTPCD), Chinese Core Journals Overview" and Coaj. It is also included in many foreign databases such as Scopus, CSA, EBSCO host, INSPEC, JST, etc.
