摘要

摘要本文提出了利用元启发式优化技术增强全球导航卫星系统（GNSS）自适应采集的方法。这项工作的主要目标是优化瑞利衰落信道中的小区平均恒误报率（CA-CFAR）阈值。在 GNSS 采集中，先导块和数据块可能具有不同的阈值。因此，优化的重点是两个缩放因子（和）。这里使用了两种融合规则（"AND "和 "OR"）。由于元启发式在不同的优化问题中表现出色，我们选择元启发式作为解决此类问题的工具。模拟结果表明，优化后的阈值对采集系统的性能有重要影响。

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
