Abstract
Narrow brand IQ signals are obfuscated by embedding the signal in a buffered portion of wideband IQ frequency data. After the data has been received and buffered, the receiving transceiver, using a wideband IQ frequency data key, of a predetermined and shared format, decodes and reconstitute the narrowband IQ signal.
