Heterodyne Detection Heterodyne detection, also known as coherent detection, is a method used in Free Space Optics (FSO) to enhance signal detection. It works by combining an incoming optical signal ...

Overview Recently, Lincoln Laboratory has achieved a speed of 100Gbps between a CubeSat manufactured by Terran Orbital in low earth orbit carrying the TBIRD payload to a ground station on Table ...

Summary The H-IIA Launch Vehicle No. 47 launched JAXA's X-Ray Imaging and Spectroscopy Mission (XRISM) and the Smart Lander for Investigating Moon (SLIM) September 7th 2023. XRISM XRISM is an X-ray ...

Summary Probabilistic Channel Models are used to describe how a communications channel will likely behave given the impact of various impairments and distortions to the transmitted signal as it passes ...

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: 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 ...
