Abstract: A system for reception of electromagnetic waves in a spectrum in which interference with radio frequencies of other electronics devices occurs comprising a transmitter; at least one receiver configured to receive the received signal; each received signal organized into a digital vector; at least one memory portion configured to store a plurality of received signals in a vector form; the vectors being combined into a matrix, each vector of the matrix being a digital data record representing a received signal; at least one processor operatively connected to the at least one memory portion; the at least one processor configured to estimate that portion of the received signal attributable to noise; the at least one processor operating to jointly estimate a minimal number of distinctive noise patterns and minimize the simplicity of the data of interest; the at least processor operating to process the noise and data of interest separately.
