摘要
阐述了用于盲均衡的恒模算法的数学模型和基本原理。对修正恒模算法、多模算法和修正多模算法进行了分析。与恒模算法相比,多模算法具有较小的剩余误差和码间干扰。修正恒模算法和修正多模算法则克服了相位偏移。针对修正多模算法存在的收敛速度慢的问题,在其误差函数的基础上给出了一种改进的多模算法。仿真结果表明,改进算法收敛速度快,剩余误差小而且能克服相位偏移,具有很好的实用性。
This paper first analysis the brigade logistics management information system stares and developmem principles. Ther it presents an introduction to the ASP.NET technology, three-tier architecture features and development process. Analysis on systerr data flow, security policies, and the module design is followed after. Descriptions on Data access hyer, business logic layer, applicatior presentation layer framework code design based on ASP.NET technology are also given. Finally the advantages of the system onerational state, and future research have been raised and discussed.
