Abstract
In this paper, we discuss the application of sequential importance sampling (SIS) to joint channel estimation and decoding of space-time trellis codes (STTC). First, we present the dynamic state space model (DSSM) of the system, and then we briefly review the theory of SIS. A special case of SIS, a combination of SIS and Kalman filtering, is shown through simulations to be a viable approach to the problem which addresses time-varying flat-fading environments. Our solution is admissible if phase ambiguity can be avoided. We show that the phase ambiguity can be reduced by carefully designing the STTC modulation constellations.
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.
