Abstract
A ternary phase shift keying transmitter and receiver can efficiently communicate using ternary encoded data that avoids indistinguishable transition curves for each of the three modulated states in the ternary encoded data. The transmitter is interoperable and can function with different types of receivers including direct detection-based receivers and coherent detection-based receivers.
Claims20
A method for processing optical data using a phase shift key (PSK) transmitter, the method comprising:
- identifying binary data for transmission;
- generating ternary modulated data from the binary data, the ternary modulated data being in a ternary PSK format comprising three modulation states;
- generating, from the ternary modulated data, non-ternary modulated data for transmission to a receiver the non-ternary modulated data being in a non-ternary PSK format that comprises more than three modulation states;
- and
- transmitting, to the receiver, the non-ternary modulated data as light using an optical source.
