ABSTRACT:
The invention features an optical spread spectrum decoder wherein linear, non-linear, and discontinuous broadband RF signals can be optically decoded.
The system introduces a weighting function into a local oscillator beam, which is then combined with a laser beam which has been modulated with the RF signal, processed to remove unwanted spectral components and then compressed. The combined beams are then down-converted to recover the RF signal.
