H ELECTRICITY
H04 ELECTRIC COMMUNICATION TECHNIQUE
H04L TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION
H04L1/00 Arrangements for detecting or preventing errors in the information received
H04L1/0001 Systems modifying transmission characteristics according to link quality, e.g. power backoff
H04L1/0015 characterised by the adaptation strategy
H04L1/0019 in which mode-switching is based on a statistical approach
H04L1/0021 in which the algorithm uses adaptive thresholds
