Abstract: The underwater acoustic channel poses a significant challenge among communication mediums due to its time-varying dynamics, long multipath propagation, and severe Doppler shifts. Ensuring ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Abstract: In an emulated IM/DD SDM system, at a fixed power budget, digital precoding increases crosstalk tolerance by 1.3 dB and 3.3 dB for PAM4 and PAM8 signaling, respectively, at the KP4 FEC BER ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...
