Mapping radio-frequency spectrum in a communication system
View Patent ↗Methods and systems for analyzing or mapping portions of the radio frequency spectrum are provided. In one embodiment of the invention, a communication method is provided, with a first step of the method including receiving an electromagnetic energy from a portion of a radio frequency spectrum. The received energy is then sampled in the time domain, and subsequently converted into the frequency domain. The sampled energy, that is now in the frequency domain is analyzed, and at least one communication parameter is selected based on the analysis of the sampled energy. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
