Abstract:
1. A method comprising: dividing a data stream into a plurality of output sub-streams, each of said output sub-streams associated with a respective spectral fragment of a first carrier signal and having a data rate compatible with a bandwidth of the respective spectral fragment, where the respective spectral fragment is one of a plurality of spectral fragments adapted for use in association with said output sub-streams, wherein the respective spectral fragment of said plurality of spectral fragments is a non-contiguous spectral block relative to said plurality of spectral fragments and separated from any other spectral fragment of said plurality of spectral fragments at least by an allocated spectral fragment not included in said plurality of spectral fragments; encrypting at least some of the sub-streams; and modulating each output sub-stream to provide a respective modulated signal adapted for transmission via said respective spectral fragment of the first carrier signal.
