Abstract
A system and method for radio frequency (RF) signal processing via photonic local oscillator (LO) phase control generates a set of N optical carriers and M sets of control inputs, each control input including an amplitude and/or phase control for the ncarrier. Each noptical carrier is split into an RF path and M LO paths, the RF path including N electro-optical (EO) modulators for amplitude/phase modulation of each ncarrier per a set of N RF input signals and each mLO path including a set of N EO modulators for amplitude/phase modulation of each ncarrier per the mcontrol input. Demodulators generate M in-phase and quadrature (I/Q) balanced optical outputs based on the multiplexed N combined RF optical outputs and each mset of N combined LO optical outputs. The M I/Q balanced optical outputs are converted to the electrical and then to the digital domain.
