MIRR

Comparison Study between Approaches of IRR and MIRR in project Evaluation

项目评估IRR法与MIRR法的比较研究

A simplified MIRR algorithm was deduced and analyzed to be used in space-time interference suppression for GPS receiver , which has low computational complexity and good performance .

在此基础上，推导分析了一种计算量小、性能优良的简化多步迭代降维（MIRR）方法，将其应用于GPS空时抗干扰中，取得良好效果。

First , the thesis compares NPV and IRR , putting great emphasis on the shortcomings of the IRR and preferring the method of MIRR ( Modified Internal Rate of Return ) as a replacement .

文章首先对净现值和内部收益率进行比较分析，着重介绍了内部收益率的先天缺陷及替代方法MIRR；

Two typical multistage iterative reduced-rank ( MIRR ) methods , multistage nested wiener filtering ( MWF ) algorithm and auxiliary vector filtering ( AVF ) algorithm were deeply analyzed and unified to the same reduced-rank frame on a certain enhanced condition .

本文深入研究了多级维纳滤波（MWF）和辅助向量滤波（AVF）两种典型多步迭代降维方法，在一定加强条件下将这两种方法统一到同一降维框架内。
