wLQ

wLQ is an acronym that appears in several domains and there is no single widely recognized meaning. The term is used in different ways depending on the context, and definitions can vary between sources.

In mathematics and control theory, wLQ is sometimes used informally to denote a weighted Linear Quadratic problem, a generalization of the Linear Quadratic Regulator. In this sense, the term describes an optimization problem where costs are weighted to emphasize certain states or inputs, potentially enabling more flexible control design or performance criteria.

In wireless telecommunications research, wLQ is sometimes used to refer to Wireless Link Quality, a metric or composite score intended to quantify the reliability and performance of a wireless connection. Such a metric might incorporate factors like signal-to-noise ratio, latency, and packet loss, but there is no universal standard for its calculation or interpretation across studies.

In computing and algorithm design, wLQ has appeared as a label for weighted quadratic constructs or as shorthand in example code. More established terms for related ideas include weighted least squares (WLS) or various forms of quadratic weighting, depending on the precise application.

Because the term wLQ has multiple meanings, readers should rely on the definition provided in the specific source material. See also Linear Quadratic Regulator, Wireless Link Quality, and Weighted Least Squares.
