  • Statistical reference criteria for adaptive signal processing in digital communications 

    Sala i Álvarez, Josep; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1997-01-01)
    Article
    Accés obert
    A general criterion for the design of adaptive systems in digital communications called the statistical reference criterion is proposed. The criterion is based on imposition of the probability density function of the ...
