a method and system for reception of electromagnetic waves in which interference with radio frequencies of other electronics devices occurs comprising ; at least one transmitter for transmitting electromagnetic radiation at a wide range of frequencies ; at least one receiver fix receiving the received signal comprising the first electromagnetic radiation and rf interfering signal data ; a first memory portion for storing transmitted signal waveforms ; a second memory portion for storing rf interfering signal data ; a switch for periodically allowing the rf interfering signal data to enter the second memory portion from the receiver ; the at least one processor operating to process and compare the received signal containing re signal data and first electromagnetic radiation by matching the received signal against data relating to the transmitted signal waveforms from the first memory portion and rf interfering signal data from the second memory portion , and extract the rf interfering signal data .
