On Resolving the Column Permutation Ambiguity in the Estimates ofMIMO System
نویسندگان
چکیده
| We consider the problem of identifying a n n MIMO system excited by unobservable non-white and spatially independent inputs. Frequency-domain methods always associate a permutation ambiguity to the system frequency response, which unless computed and compensated for, results in an erroneous solution. We show that, from the permutation-dependent solution we can extract some quantities (invariances) which are independent of the permutation, and which, under certain conditions, can lead to the correct solution.

Gesture and its impact of resolving lexical ambiguity
The study aimed to shed light on the use of gesture in resolving lexical ambiguity employed by TEFL students. To this end, 60 intermediate Iranian learners, studying at Kish Way Language School in Iran were recruited. The participants were randomly put into two experimental groups and one control group. Both of the experimental groups received the same teaching approach, i.e. teaching homonyms ...
متن کاملEvaluation of the Regularization Algorithm to Decorrelation of Covariance Matrix of Float Ambiguity in Fast Resolution of GPS Ambiguity Parameters
Precise positioning in Real Time Kinematic (RTK) applications depends on the accurate resolution of the phase ambiguities. In RTK positioning, ambiguity parameters are highly correlated, especially when the positioning rate is high. Consequently, application of de-correlation techniques for the accurate resolution of ambiguities is inevitable. Phase ambiguity as positioning observations by the ...

In this paper, a new algorithm is introduced for localization of multiple speakers in echoic environments. The origin of localization is based on combination of TDOA estimates of each source obtained by the BSS algorithm in the time domain. A new BSS algorithm is proposed which improves the quality and channel identification compared to a reference technique and also reduces the computational c...

متن کاملResolving Plan Ambiguity for Cooperative Response Generation
Recognizing the plan underlying a query aids in the generation of an appropriate response In this paper we address the problem of how to generate cooperative responses when the user s plan is ambiguous We show that it is not al ways necessary to resolve the ambiguity and provide a procedure that estimates whether the ambiguity matters to the task of formulating a response If the ambiguity does ...
