Abstract:
We consider the approach that allows to separate rays in the quasi-stationary radio channel in shortwave bands. The considered approach can be used when the Doppler filtration, angles of arrival, polarization, and delays cannot separate rays. The received signal is a result of interference of several rays. In this case the problem of ray separation is non-correct and allows the set of solutions. The non-quadratic regularization using to non-correct problems is considered in this paper. Using the non-quadratic regularization allow us to obtain higher resolution than spectrum methods.
