Novel Unipolar Orthogonal Frequency Division Multiplexing (U-OFDM) for Optical Wireless
2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012A novel modulation technique coined U-OFDM is proposed. U-OFDM uses different time sample states and an innovative rearrangement of the Orthogonal Frequency Division Multiplexing (OFDM) frame which allow for the creation of unipolar OFDM signals required for Optical Wireless Communication (OWC) with Light Emitting Diodes (LEDs).

Design and Simulation of Orthogonal Frequency-Division Multiplexing (OFDM) Signaling
, 2021 The orthogonal frequency-division multiplexing (OFDM) is a modulation scheme which is spectrally efficient and which decomposes one carrier into several subcarriers. Each subcarrier is orthogonal, allowing the transfer of data on each subcarrier simultaneously.

Interference mitigation in orthogonal frequency division multiplexing (OFDM)
Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2002Orthogonal frequency division multiplexing (OFDM) is a modulation scheme purported to be insensitive to the multipath effects of a mobile communication channel as well as exhibiting immunity to narrow-band interference via hole punching in the OFDM spectrum.

Orthogonal Frequency Division Multiplexing (OFDM)
2008 China-Japan Joint Microwave Conference, 2008In broadband wireless system, the signal energy is scattered and reflected from objects in the environment, components of the signal arriving at the receiver are spread out over a longer period of time than is desirable. The challenge is then to provide a high-performance reliable data link that can operate with the restricted receiver power levels ...

Analysis of the effects of phase-noise in orthogonal frequency division multiplex (OFDM) systems
Proceedings IEEE International Conference on Communications ICC '95, 2002In OFDM transmission schemes, phase-noise from oscillator instabilities in the receiver is a potentially serious problem, especially when bandwidth efficient, high order signal constellations are employed. The paper analyses the two effects of phase-noise: inter-carrier interference (ICI) and a phase error common to all OFDM sub-carriers.

Orthogonal Frequency Division Multiplex (OFDM)
2004Almost from the beginning of the electrical transmission of messages about 100 years ago, single-carrier methods have been used for transmitting information. The message to be transmitted is impressed on a sinusoidal carrier by applying analog amplitude, frequency or phase modulation techniques.

Developments in orthogonal frequency division multiplexing (OFDM) system-a survey
2011 Second Asian Himalayas International Conference on Internet (AH-ICI), 2011In today's communication scenario, high data rate single-carrier transmission may not be feasible due to too much complexity of the equalizer in the receiver. To overcome the frequency selectivity of the wideband channel experienced by single-carrier transmission, multiple carriers can be used for high rate data transmission.
