Abstract:
1. A method, comprising: Receiving, by a modulator implemented as hardware logic in a transmitter, a two-bit information stream comprising first and second bits; performing, by the modulator, precoding using the two-bit information stream to determine a plurality of output signals, the precoding performed to create a finite plurality of states for the output signals, wherein the output signals comprise a first output signal based on a version of the first input bit and on a version of a second input bit, a second output signal based on a delayed version of the first input bit and the version of the second input bit, and a third output signal based on the version of first input bit and a delayed version of the second input bit; performing, by the modulator, pulse shaping of each of the output signals to create pulse-shaped signals; combining, by the modulator, the pulse-shaped signals to create a transmission waveform; and outputting, by the modulator, the transmission waveform.
