一种基于蚁群融合的盲传输格式检测方法

[摘要] 针对现有3GPP标准中盲传输格式检测方案的性能不足，文章结合蚁群算法和融合量的特点提出了一种适用于WCDMA终端的盲传输格式检测算法。该算法利用蚁群信息量记忆传输格式历史数据，对不同判据的可靠性程度进行加权融合。仿真结果表明：文章提出的方法在多应用场景下均明显提高了WCDMA终端中盲传输格式检测的可靠性。

[Abstract] In this paper, a new blind transport-format detection method based on ant colony merge algorithm for WCDMA systems is proposed. The method is designed to alleviate detriments to link performance using currently available blind-transport- format algorithms. Such algorithms use the ant colony to remember historical information about the transport format, and merge the detection judgment according to the reliability. Simulations show that the proposed algorithm significantly improves link performance in all practical scenarios.
