摘要： The present disclosure provides for methods and systems for segmented spread-spectrum communication according to one embodiment of the invention. Segmented spread-spectrum communication may include replicating a signal, spreading each of the replicated signals with a code, and modulating each of the coded signals within a unique spectral segment. The spectral segments may be uniform or nonuniform in width and may or may not be contiguous within the spectrum. The receive processing may include interference detection within a spectral segment. In response to detected interference, spectral segments may be discarded, a signal gain of each segment may be adjusted according to the level of interference, and/or selected segments may be adjusted according to the level of interference. Moreover, at the receiver a number of transmitted spectral segments may be combined. As a further embodiment, a plurality of signals may spread among a plurality of spectral segments.
