TL;DR: In this paper, the performance of spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) systems based on single photo-diode (SPD) detection under various types of optical filters decoder schemes (Optical Gaussian filter, Thin film and Fiber Bragg Grating (FBG)).

TL;DR: A new technique to mitigate turbulence-induced intensity fluctuations, i.e., signal fading (under the effects of rain and haze) is described, which determines the priority in the optimization of transmission parameters to achieve high data rate transmission with low link attenuation and bit-error rate.

TL;DR: In this article, the performance of different channel spacing with AND as well as modified-AND subtraction detection techniques emphasizing the spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) systems was analyzed.

TL;DR: In this paper, a new code structure for spectral amplitude coding in optical code division multiple access (OCDMA) systems called Random Diagonal (RD) code is proposed, which is constructed using code level and data level, and the important properties of this code is that the cross correlation at data segment is always zero, which means that phase intensity induced noise (PII) is reduced.

TL;DR: A new scheme of rake receivers was proposed to receive indoor, multi-path components (MPCs) for ultrawideband (UWB) wireless communication systems, and coefficients for a continuous wavelet transform (CWT), a discrete wavelettransform (DWT), and an inverse, discrete wavel et transform (IDWT) are proposed.
