Optical wireless communication (OWC), with intensity modulation (IM), requires the modulated radio frequency (RF) signal to be real and non-negative. To satisfy the requirements, this paper proposes a novel mixed orthogonal frequency division multiplexing (X-OFDM) waveform. Hermitian symmetry (HS) of the sub-carriers in frequency domain, guarantees the

2012 8th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2012
We propose to achieve scalable O-OFDM network planning with a genetic algorithm (GA) that operates in an adaptive way for high optimization efficiency. When the network topology and lightpath requests are given, the GA encodes the routing, spectrum and modulation assignments (RSMA) as genes and optimizes them iteratively.

A comparison of timing methods in orthogonal frequency division multiplexing (OFDM) systems
2012Orthogonal frequency division multiplexing (OFDM) is being used by wireless local area network (WLAN) standards, such as IEEE 802.11a, and wireless metropolitan area network (MAN) standards, such as IEEE 802.16a. OFDM is a very efficient communications scheme for wireless ADHOC networks.
