Patent ID: 6847678

Claim:
A system for generating an adaptive air interface waveform, the system comprising: an adaptive multi-carrier organization and signaling component operable to generate a waveform having a multi-carrier organization comprising a variable carrier frequency and variable bandwidth signal that comprises one or more subcarriers that are dynamically placeable over a range of frequencies, each subcarrier being separately modulated according to a direct sequence (DS) spread spectrum (SS) modulation technique, the waveform having an embedded pilot usable to optimize one or more spectrum efficiencies of the waveform; and an adaptive multi-level bandwidth-efficient coding and modulation (BECM) component receive the waveform from the adaptive multi-carrier organization and signaling component, the BECM component operable to adapt a modulation constellation, a code rate, and a code length of the waveform according to an available spectrum and one or more varying conditions of the subcarrier in order to provide the waveform as the adaptive air interface waveform.
