Laboratory and space spectroscopy of DCO+ [PDF]
The rotational spectra of DCO+ and its two isotopomers D{13}^CO+ and DC{18}^O+, produced in a negative glow discharge cell, have been recorded in the 137-792 GHz region, which includes lines from J=2-1 up to J=11-10. The determined rotational and centrifugal distortion constants allow to predict the DCO+ rotational spectrum up to 1000 GHz with an ...

Anscombe Root DCO-OFDM for SPAD-Based Visible Light Communication
For high-speed visible light communication (VLC) with weak signals such as in underwater environment, dc-biased optical orthogonal frequency-division multiplexing (DCO-OFDM) based on single-photon avalanche diodes (SPADs) is viewed as a promising scheme.

DCO-OFDM Channel Sounding with a SiPM Receiver
Orthogonal Frequency-Division Multiplexing (OFDM) is a popular modulation scheme, which requires a linear channel. Unfortunately, the most sensitive receivers for visible light communications, silicon photomultipliers (SiPMs), have a non-linear response. Despite this incompatibility, results from an easily implemented method of combining OFDM and SiPMs
