  2. WSPR (amateur radio software) - Wikipedia

    en.wikipedia.org/wiki/WSPR_(amateur_radio_software)

    It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT. The software code is now open source and is developed by a small team.

    The program was initially written by Joe Taylor, K1JT, but is now open source and is developed by a small team. The digital signal processing techniques in WSJT-X make it substantially easier for amateur radio operators to employ esoteric propagation modes, such as high-speed meteor scatter and moonbounce .

    In August 2018, she started designing the appearance for Hololive Production's Virtual YouTuber Oozora Subaru, [4] who debuted in September the same year. [6] Since then, she occasionally appears as a guest on Hololive member livestreams , particularly with Subaru and Miko. [ 3 ]

  5. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

  6. Matrix decoder - Wikipedia

    en.wikipedia.org/wiki/Matrix_decoder

    Matrix decoding is an audio technology where a small number of discrete audio channels (e.g., 2) are decoded into a larger number of channels on play back (e.g., 5). The channels are generally, but not always, arranged for transmission or recording by an encoder, and decoded for playback by a decoder.

    en.wikipedia.org/wiki/Pirate_decryption

    The question of signal substitution, by which Canadian cable and satellite providers substitute the signal of a local or domestic channel over a foreign or distant channel carrying the same program, is rendered more complex by the existence of a reverse grey market. Signal substitution had already been the cause of strong diplomatic protests by ...

  8. Subaru Global Platform - Wikipedia

    en.wikipedia.org/wiki/Subaru_Global_Platform

    The Subaru Global Platform (スバルグローバルプラットフォーム), abbreviated as SGP, is the modular unibody automobile platform for nearly all models manufactured by Subaru, starting with the fifth-generation Subaru Impreza in 2016. [2]

  9. Low-density parity-check code - Wikipedia

    en.wikipedia.org/wiki/Low-density_parity-check_code

    As with other codes, the maximum likelihood decoding of an LDPC code on the binary symmetric channel is an NP-complete problem, [24] shown by reduction from 3-dimensional matching. So assuming P != NP , which is widely believed, then performing optimal decoding for an arbitrary code of any useful size is not practical.
