Abstract
Various embodiments of the invention are directed to orthogonal frequency chirp multiple accessing (OFCM) systems and methods. For example, various embodiments of the OFCM transmitter may utilize an architecture comprised of a baseband modulation subsystem, a subsystem for generating multiplicity N orthogonal frequency chirp waveforms, and a bank of multiplicity N spread spectrum modulators. Various embodiments of the OFCM receiver may comprise of a subsystem for generating complex conjugates of multiplicity N orthogonal frequency chirp waveforms, a bank of multiplicity N spread spectrum demodulators, a symbol estimator, a symbol timing estimator, a frequency offset estimator, a carrier phase tracking loop, a multi channel estimator, and a baseband demodulation subsystem.
