Abstract
A spread spectrum receiving method receives a spread spectrum signal. An optical signal frequency comb is generated. Modes of the optical signal frequency comb are modulated with a received spread spectrum signal. An optical local oscillator comb is generated that is mutually coherent with the signal frequency comb. A code word is applied to the local oscillator comb. The combs are combined and the received spread spectrum signal is detected from the combined combs.
Claims9
A method for receiving a spread spectrum signal, the method comprising generating an optical signal frequency comb, modulating modes of the optical signal frequency comb with a received spread spectrum signal, generating an optical local oscillator comb that is mutually coherent with the signal frequency comb, applying a codeword to the local oscillator comb, combining the combs and detecting the received spread spectrum signal from the combined combs.
