    Abstract: A method for implementing Polarization Division Multiplexing Binary Phase Shift Keying (PDM-BPSK) modulation and Quadrature Phase Shift Keying (QPSK) modulation in a compatible manner includes: dividing a direct current (DC) light into a first channel of light and a second channel of light with the same power; separately performing optoelectrical modulation on the first channel of light and the second channel of light and correspondingly outputting a first optical signal and a second optical signal in a Binary Phase Shift Keying (BPSK) format; performing polarization state control on the first optical signal; performing a phase shift on the first optical signal or the second optical signal; and performing optical signal combination with the polarization state preserved on the first optical signal and the second optical signal after the polarization state control and the phase shift, and outputting a PDM-BPSK modulation optical signal or a QPSK modulation optical signal.

    Abstract: A radio frequency (RF) transmitter has at least one digital signal processing module and at least one power amplifier module. The digital signal processing module includes at least one digital pre-distortion component arranged to receive at least one complex input signal, perform two-dimensional non-uniform mapping of the complex input signal to a first, in-phase, digital pre-distortion control word and a further, quadrature, digital pre-distortion control word, and output the in-phase and quadrature pre-distortion digital control words. The power amplifier module includes a first, in-phase, array of switch-mode power cells and at least one further, quadrature, array of switch-mode power cells. The two-dimensional non-uniform mapping has a pre-distortion profile at least partly based on an input/output relationship for the power amplifier module arranged to generate an analogue RF signal based at least partly on the in-phase and quadrature digital pre-distortion control words.
