In adaptive [[high-frequency]] (HF) radio, '''link quality analysis''' ('''LQA''') is the overall process by which measurements of [[radio signal]] quality are made, assessed, and analyzed.

In LQA, signal quality is determined by measuring, assessing, and analyzing [[Telecommunications link|link]] parameters, such as [[bit error ratio]] (BER), and the levels of the ratio of signal-plus-[[noise]]-plus-[[distortion]] to noise-plus-distortion ([[SINAD]]). Measurements are stored at—and exchanged between—stations, for use in making decisions about link establishment.

For adaptive HF radio, LQA is automatically performed and is usually based on analyses of pseudo-BERs and SINAD readings.
