Overview The FFT (Fast Fourier Transform) converts time-domain signals into frequency-domain signals, while the IFFT (Inverse Fast Fourier Transform) does the reverse, converting frequency-domain ...

Summary: Tranche 0 refers to the first deployment of LEO satellites by the Space Development Agency (SDA) for the DoD, as a demonstrator for later tranches as the Proliferated Warfighter Space ...

Overview An Optical Frequency Comb Generator (OFCG) is utilized in optical communication systems to generate a series of discrete, equally spaced frequency lines (or "teeth" on a frequency "comb" when ...

Overview SISO and MIMO refer to arrangements of optical transmitters and receivers. SISO systems are generally simpler but have lower data rates while MIMO systems are more complex and robust against ...

Paper Summary: In order to meet demand from IoT devices, 5G and beyond new Optical wireless communication (OWC) systems covering an ultra-wide range of unlicensed spectrum (in particular near ...

Paper Summary: A new coding method for optical code division multiple access (OCDMA) is proposed, referred to as three-dimensional spectral/temporal/spatial single weight zero cross-correlation code. ...

Paper Summary: Optical Code Division Multiple Access (OCDMA) is a type of multiplexing technique that allows several users to share the same fiber-optic link by assigning each of them a unique optical ...

Summary Underwater Optical Communication (UWOC) is a type of FSO communication for underwater applications. The increased density of water compared to air makes challenges such as absorption, ...

Overview Random Unitary Beamforming (RUB) is a beamforming technique that was originally developed for Multiple-input multiple output (MIMO) wireless systems. In Free-space optical (FSO) ...

Overview LiDAR which is an acronym for light detection and ranging is a method of remote sensing. This method consists of illuminating an object plane with a laser source and capturing the reflected ...
