Robust Wiener Design of Adaptation Laws with Constant Gains

Tracking of time-varying mobile radio channels .1. The Wiener LMS algorithm

Adaptation algorithms with constant gains are designed for tracking smoothly time-varying parameters of linear regression models, in particular channel models occurring in mobile radio communications. In a companion paper, an application to channel tracking in the IS-136 TDMA system is discussed. The proposed algorithms are based on two key concepts. First, the design is transformed into a Wien...

Wiener design of adaptation algorithms with time-invariant gains

A design method is presented that extends least mean squared (LMS) adaptation of time-varying parameters by including general linear time-invariant filters that operate on the instantaneous gradient vector. The aim is to track time-varying parameters of linear regression models in situations where the regressors are stationary or have slowly time-varying properties. The adaptation law is optimi...

Adaptation with constant gains: analysis for slow variations

Lars Lindbom, Mikael Sternad and Anders Ahlén Signals and Systems, Uppsala University, PO Box 528, SE-75120, Uppsala, Sweden. [email protected], ms,aa @signal.uu.se Abstract: Adaptation laws with constant gains, that adjust parameters of linear regression models, are investigated. The class of algorithms includes LMS as its simplest member. Closed-form expressions for the tracking MSE...

Assessment of impact of climate change on potato and potential adaptation gains in the Indo-Gangetic Plains of India

India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...
