DCO-OFDM Channel Sounding with a SiPM Receiver
2021 IEEE Photonics Conference (IPC), 2021 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

Anscombe Root DCO-OFDM for SPAD-Based Visible Light Communication
IEEE Photonics Journal, 2018 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.

A Scalable DCO Design for Portable ADPLL Designs [PDF]
2005 IEEE International Symposium on Circuits and Systems, 2005 A novel digital controlled oscillator (DCO) design methodology is presented in this paper. The new design methodology includes a scalable DCO architecture and the developed design flow. With precise analysis in early stage, the design effort of DCO can be reduced significantly.

An Energy-Efficient ADO-OFDM System for Optical Wireless Communication
IEEE Photonics Journal, 2023 This paper proposes an energy-efficient asymmetrically clipped direct-current (DC) biased optical orthogonal frequency division multiplexing (EEADO-OFDM) scheme, which replaces the fixed DC bias of DC biased optical OFDM (DCO-OFDM) branch with a adaptive
