An Improved Blind Spectrum Sensing Technique for Cognitive Radio Systems

International Journal of Information and Communication Technology Research, 2011
Cognitive radio technology has been proposed as a key solution for the problem of inefficient usage of spectrum bands. Spectrum sensing is one of the most important issues in each cognitive radio system.

Evaluation of blind signal separation methods

, 1999
Recently many new Blind Signal Separation BSS algorithms have been introduced Authors evaluate the performance of their algorithms in various ways Among these are speech recognition rates plots of separated signals plots of cascaded mixingunmixing impulse responses and signal to noise ratios Clearly not all of these methods give a good reection of the ...

BLIND SIGNAL SEPARATION APPLICATIONS AND METHODS

Енергозбереження. Енергетика. Енергоаудит.
Blind signal separation is the task of separating the given mixture signal into two or more corresponding sources. It finds an application in many fields of human activity such as medicine, telecommunications, art and many more and is a crucial task in signal processing.
