Pseudo bit error ratio (PBER) in adaptive
high-frequency (HF)
radio, is a
bit error ratio derived by a majority decoder that processes redundant transmissions.
''Note:'' In adaptive HF radio
automatic link establishment Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. ALE is a feature in an HF communications radio transceiver system that enables the radio statio ...
, PBER is determined by the extent of error correction, such as by using the fraction of non-unanimous votes in the 2-of-3 majority decoder.
