In this letter, we first present the theoretical basis for coherent optical OFDM systems in direct
up/down conversion architecture. We then demonstrate the transmission performance …

For future short-range applications, optical wireless communications present a viable and
promising supplemental technology to radio wireless systems. This contribution presents a …

The merit of evolutionary algorithms (EA) to solve convex optimization problems is widely
acknowledged. In this paper, a genetic algorithm (GA) optimization based waveform design …

In this paper, we investigate the ultimate performance limits, in terms of achievable
information rate (IR), of communication systems impaired by impulse noise. We compare …

Sequences and their properties have been studied widely in different research areas
because they have useful characteristics which are used in many applications. Correlation …

Frequency agility is an important feature when radar operates in jammed environments. With
the development of the orthogonal frequency division multiplexing (OFDM) waveform in the …

Underwater acoustic communications are limited by the following channel impairments: time
variability, narrow bandwidth, multipath, frequency selective fading and the Doppler effect …

Although polarization-mode dispersion (PMD) greatly impairs conventional high-speed
single-carrier systems, it is shown that for multicarrier systems such as coherent optical …

In this letter, we conduct analysis on the optimum design for RF-to-optical up-converter in
coherent optical OFDM systems using an optical I/Q modulator. We first derive closed-form …

Interleave-Division Multiple Access (IDMA) is a multi-user scheme in which chip interleavers
are the only means of user separation. The receiver involves a chip-by-chip iterative multi …
