Effect of Correlated Non-Gaussian Quadratures on the Performance of Binary Modulations [PDF]
Journal of Electrical and Computer Engineering, 2011 The received signal in many wireless communication systems comprises of the sum of waves with random amplitudes and random phases. In general, the composite signal consists of correlated nonidentical Gaussian quadrature components due to the central ...

On Generalized Gaussian Quadratures for Exponentials and Their Applications
Applied and Computational Harmonic Analysis, 2002 We introduce new families of Gaussian-type quadratures for weighted integrals of exponential functions and consider their applications to integration and interpolation of bandlimited functions.We use a generalization of a representation theorem due to ...

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2009 Using a special psi-function the paper presents an exact and approximate (with an error evaluation) solutions of the mixed problem pertaining to one-dimensional heat conduction equation. An advantage of the obtained approximate formula is its comparative
