Maximum a posteriori equalizer
A maximum a posteriori (MAP) equalizer is a receiver component that estimates each transmitted symbol by maximizing its posterior probability, most commonly implemented with the BCJR algorithm of 1974.
Maximum allowable operating pressure
Maximum allowable operating pressure (MAOP) is the highest pressure at which a pipeline segment may be operated under US pipeline safety regulation, set by 49 CFR § 192.619.
Maximum flow problem
The maximum flow problem, introduced by Ford and Fulkerson in 1956, asks for the greatest possible flow through a directed network from a source to a sink.
Maximum likelihood channel estimation
Maximum likelihood channel estimation is a method that estimates a communication channel's response by choosing the channel coefficients that maximize the likelihood of the received data samples.
Maximum likelihood detection
Maximum likelihood detection is a digital communications method that selects the transmitted symbol or sequence most likely to explain the received signal, minimizing error when symbols are equally likely.
Maximum likelihood sequence estimation
Maximum likelihood sequence estimation (MLSE) is a digital communications receiver method that estimates an entire symbol sequence, minimizing error on channels with intersymbol interference and Gaussian noise.
Maximum power point tracking
Maximum power point tracking (MPPT), typically performed by an inverter or DC-DC converter, continuously adjusts a photovoltaic array's operating point to deliver the greatest power available as sunlight and temperature vary.
Maximum ratio combining
Maximum ratio combining (MRC) is a diversity reception technique in which a receiver weights independently faded copies of a signal so they add coherently, achieving the highest possible output SNR.
Maximum ratio transmission
Maximum ratio transmission (MRT), also called conjugate beamforming, is a linear precoding technique that aligns each base station transmit signal with the user's channel vector.
Maximum subarray problem
The maximum subarray problem, also called the maximum segment sum problem, asks for a contiguous array stretch with the largest possible sum; Kadane's algorithm solves it in linear time.
Maximum transmission unit
The maximum transmission unit (MTU) is the largest packet or frame, measured in octets, that a network link can send in one piece, 1500 bytes for standard Ethernet.
Maximum-likelihood MIMO detection
Maximum-likelihood MIMO detection (ML detection, MLD) is the optimal receiver algorithm for MIMO wireless systems, minimizing the Euclidean distance between the received vector and possible transmitted signals.
Maxis Communications
Maxis Communications, formally Maxis Communications Berhad, is a Malaysian integrated telecommunications company whose mobile service launched in 1995 and became one of Malaysia's leading operators.
MaxLinear
MaxLinear is an American fabless semiconductor company founded in Carlsbad, California in 2003, designing communications chips for broadband access, 5G wireless infrastructure, and data center connectivity.
MaxMatch
MaxMatch names several distinct things: a Ludii graph theory game (DLP.Game.546 by Tahmina Begum), a deterministic 2-rank-approximation mechanism for matching markets, a 2022 semi-supervised learning method, and competitive-programming problems and function names for maximum matching.
Maxon Group
Maxon Group is a Swiss family-owned manufacturer of high-precision electric drive systems based in Sachseln, founded in 1961, whose motors have powered NASA Mars rovers, surgical tools, and humanoid robots.
MAXQ hierarchical reinforcement learning
MAXQ is a hierarchical reinforcement learning method introduced by Thomas G. Dietterich in 2000 that decomposes a task into smaller subtasks and their value functions, converging faster than flat Q-learning.
Maxthon
Maxthon, formerly MyIE2, is a freeware web browser from the Chinese company Maxthon, built on Chromium, available for Windows, macOS, Android, and iOS since its 2004 renaming.
Maxus (大通)
Maxus, also known as SAIC Maxus, is a Chinese commercial and passenger vehicle brand owned by SAIC Motor, founded in 2011 and sold in more than 120 countries.
Maxus Terron 9
Maxus Terron 9 (Chinese name Interstellar X, 星际X): SAIC Maxus's large 5,500 mm dual-cab pickup built at Wuxi since 2024, sold as the diesel Terron 9 and electric eTerron 9 (325 kW, 102.2 kWh, 430 km WLTP), exported to Europe, Australia, Latin America, and Asia.
Maxwell (microarchitecture)
Maxwell is a Nvidia GPU microarchitecture, successor to Kepler, introduced in 2014 with the GeForce GTX 750 Ti and known for major gains in performance per watt.
Maxwell coupling
A Maxwell coupling is a kinematic coupling in which three balls in three V-shaped grooves give six contact points that exactly constrain six degrees of freedom.
Maxwell Technologies
Maxwell Technologies is an American energy-storage company in San Diego, California, known for ultracapacitors used in cars, wind turbines, and grids, with origins dating to 1965.
Maxwell's Daemon
Maxwell's Daemon (maxwell) is Zendesk's open-source MySQL-only change data capture tool: a single Java process that reads MySQL binlogs and emits JSON row-change events to Kafka, Kinesis, RabbitMQ, Redis, Pub/Sub, and BigQuery. Not the physics thought experiment.
