The National Center for Biotechnology Information (NCBI) Taxonomy is widely applied in biomedical and ecological studies.Typical demands include querying taxonomy identifier (Taxlds) by taxonomy names,querying complete taxonomic lineages by Taxlds,listing descendants of given Taxlds,and others.How-ever,existed tools are either limited in functionalities or inefficient in terms of runtime.in this work,we present TaxonKit,a command-line toolkit for comprehensive and efficient manipulation of NCBI Taxonomy data.TaxonKit comprises seven core subcommands providing functions,including Taxlds querying,listing,filtering,lineage retrieving and reformatting,lowest common ancestor computation,and Taxlds change tracking.The practical functions,competitive processing performance,scalability with different scales of datasets and good accessibility can facilitate taxonomy data manipulations.TaxonKit provides free access under the permissive MIT license on GitHub,Brewsci,and Bioconda.The documents are also available at https://bioinf.shenwei.me/taxonkit/.

针对复杂电磁环境和非协作通信条件下空频分组码(space-frequency block codes,SFBC)信号识别困难、对先验信息要求高的问题,提出一种基于频域互相关序列与峰值检测的SFBC盲识别方法.首先,通过分析SFBC信号的编码特点,计算得到发送端的互相关函数.然后,考虑频率选择信道、多径传播和噪声的影响,推导了接收信号的互相关函数,并对其进行傅里叶变换得到频域互相关序列.最后,根据频域互相关序列检测其峰值位置识别发射端编码方式.推导和实验结果表明,该算法在低信噪比下的识别性能较好,并且对时间
