Abstract:
1. A method for encoding a label in a quaternary phase shift keying signal, comprising: combining, by an encoder, a label frame comprising a binary encoding of the label, a binary signature sequence for code-division multiple access, and a first binary data payload into a first composite data stream, wherein the label frame comprises a plurality of blocks, wherein the binary encoding of the label is defined by a constant number of phase transitions per block, each block having a predetermined number of bits, wherein the constant number of phase transitions per block defines the label as compared to other labels; deinterleaving, by the encoder, the first composite data stream into a first data stream and a second data stream; and precoding, by the encoder, the first data stream and the second data stream to output a respective first quaternary phase shift keying tributary and a second quaternary phase shift keying tributary, wherein the quaternary phase shift keying signal is a dual polarization quaternary phase shift keying signal, and the first quaternary phase shift keying tributary and the second quaternary phase shift keying tributary are a respective first tributary and a second tributary of a first polarization of the dual polarization quaternary phase shift keying signal.
