Phase-shift-keying (PSK) self-homodyne modulation and demodulation using a polarization-multiplexed pilot-carrier with an inverse-return-to-zero (RZ) intensity modulation signal for 2-bit/symbol ...

We design and implement an optical phase estimator for carrier synchronization of a homodyne receiver for weak coherent states, based on sequential I-Q measurements. We report experimental results on ...

AstraZeneca has turned to another digital health partner to support its aspirations in chronic kidney disease (CKD), joining forces with Aptar to develop algorithms that can be used to detect CKD ...
