To improve data transmission reliability and reduce computational complexity in ultra-wideband(UWB)sys-tems,a Turbo-CS coding technique is introduced.Through Monte Carlo simulations and analysis,the bit error rate(BER)and convergence speed of UWB systems are compared.To ensure fair comparison,the wireless indoor environ-ment is modeled as the modified Saleh-Valenzuela(SV)channel model proposed by IEEE 802.15.3a,and the LOG-MAP algorithm is employed uniformly.Simulation results demonstrate that,compared with the uncoded and Turbo-coded UWB systems,the system employing Turbo-CS coding achieves significantly better BER performance and computational efficiency.
Based on the definitions of fuzzy associative algebras and fuzzy ideals, it is proven that the intersections of fuzzy subalgebras are fuzzy subalgebras, and the intersections of fuzzy ideals are fuzzy ideals. Moreover, we prove that the kernels of fuzzy homomorphisms are fuzzy ideals. Using fuzzy ideals, the quotient structures of fuzzy associative algebras are constructed, their corresponding properties are discussed, and their homomorphism theorems are proven.
马克思主义人的全面发展理论为构建"三全育人"的科学路径提供了指南.高职院校的"三全育人"工作一要破除制约大学生全面发展的盲目必然性,做到有的放矢;二要基于"三全育人"的特殊性,张扬大学生个性,培养卓越人才;三要立足于"三全育人"的普遍性,让大学生"占有自己的全面本质",培养大众化技能人才."三全育人"工作通过充分挖掘大学生的潜能,提升其综合素质,培养自由全面发展的人,为实现中华民族的伟大复兴增添动力.

建构"专题式教学"模式,是高校思政课教学模式的革新,有助于推进大中小学思政课教学内容的有机衔接,提高高校思政课教学的针对性和实效性;有助于推动高校教师教学与科研的协同发展;有助于增加大学生思政课学习的获得感.建构"专题式教学"模式,教学内容的专题设计是重中之重,要遵循目标与手段、规律与价值、内容与形式的辩证统一原则.实现"专题式教学"需要遵循四条路径:一是将整体教学目标贯通于专题教学各个环节;二是教学创新必须遵循教育教学规律、学生认知规律和思想政治教育规律;三是深耕各学段思政课教材;四是加强教学与科研的协同、思政课教师与专业课教师的协作.
