Abstract: A system and method for performing perceptually-transparent RTF estimation for a two-channel system with low estimation errors. The system includes two loudspeakers for the left and right channels positioned in a room and a single microphone, positioned in the vicinity of a listener in the room. The system performs spectral splitting using a filter bank and a complementary filter bank, to obtain separation in frequency between the two channels. Calibration signals being uncorrelated across the two channels are, generated using the original audio signals and the constructed filters. Then, the calibration signals are played back by the loudspeakers, instead of playback of the original audio signals. At the end, the system records the playback of the calibration signals by the microphone and simultaneously estimates the two-channel RTF using the recorded played back calibration signals.

Abstract: A method for compensating the distortions introduced by impairments of MZMz implementing an optical transmitter, according to which the level of total amplitude and phase distortions caused by the optical transmitter is measured and all impairments in the constellation domain are compensated by pre-distorting the input signal to be transmitted by symmetrically adding imbalance to the voltage applied to the MZM arms. The imbalance is determined by introducing a phase rotation in either I or in the Q path of the optical transmitter, which compensates the total amplitude distortion, and also introducing a phase rotation to both I and Q paths of the optical transmitter, which compensate the total phase distortion and the phase shift caused by compensating the amplitude distortion, until reaching a desired operating point, which corresponds to the level of pre-distortion.

Abstract: Disclosed are a method for achieving ultrahigh spectral resolution and a photonic spectral processor, which is designed to carry out the method. The disclosed photonic spectral processor overcomes the current 0.8 GHz spectral resolution limitation. The new spectral processor uses a Fabry-Perot interferometer array located before the dispersive element of the system, thus significantly improving the spectral separation resolution, which is now limited by the full width at half maximum of the Fabry-Perot interferometer rather than the spectral resolution of the dispersive element spectral as is the current situation. A proof of concept experiment utilizing two Fabry-Perot interferometers and a diffractive optical grating with spectral resolution of 6.45 GHz achieving high spectral resolution of 577 MHz is described.
