Història natural de les malalties genètiques mendelianes i complexes

Lao Grueso, Oscar, 1976- (Universitat Pompeu Fabra, 2004-11-26)

Las enfermedades genéticas se clasifican típicamente en dos grandes grupos: las enfermedades mendelianas y las enfermedades complejas. Mientras que las enfermedades mendelianas se caracterizan por ser de baja frecuencia ...
Advanced decoding algorithms for satellite broadcasting

Lamarca, Meritxell; Sala, Josep; Rodríguez, Eduardo; Martínez, Alfonso (Springer, 2005)

The evaluation of the union bound for theber of Reed-Solomon/Convolutional concatenated codes indicates that their performance might largely improve through the application of soft iterative decoders. This paper presents ...
Extremes of error exponents

Guillén i Fàbregas, Albert; Land, Ingmar; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2013)

This paper determines the range of feasible values of standard error exponents for binary-input memoryless symmetric channels of fixed capacity C and shows that extremes are attained by the binary symmetric and the binary ...
Mismatched decoding: error exponents, second-order rates and saddlepoint approximations

Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)

This paper considers the problem of channel coding with a given (possibly suboptimal) maximum-metric decoding rule. A cost-constrained random-coding ensemble with multiple auxiliary costs is introduced, and is shown to ...
Expurgated random-coding ensembles: exponents, refinements and connections

Scarlett, Jonathan; Peng, Li; Merhav, Neri; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)

This paper studies expurgated random-coding bounds and exponents for channel coding with a given (possibly suboptimal) decoding rule. Variations of Gallager's analysis are presented, yielding several asymptotic and ...
