Abstract :
The authors consider multipath propagation in which one or more attenuated and delay versions of the same radiated signal are received at a single sensor or a beamformed array of sensors. They propose a probabilistic model for the eigenvalues and investigate the use of the theory of moments to obtain an approximation to the eigenvalues of a homogeneous Fredholm integral equation of the second kind and Hermitian kernel. A numerical example to demonstrate the performance of the technique proposed is presented
