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

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.

Future, high bit rate communication systems tolerate very little error in the modulation. This means that conventionally negligible error sources like the imbalance between the in-phase (I) and quadrature (Q) branches of the receiver can start limiting the performance of the system.
