14.3.8.1 Overview
During symbol detection within frame reception, the AT86RF212B uses correlation results of multiple symbols in order to compute an estimate of the LQI value. This is motivated by the fact that the mean value of the correlation result is inversely related to the probability of a detection error.
LQI computation is automatically performed for each received frame, once the SHR has been detected. LQI values are integers ranging from zero to 255 as required by the IEEE 802.15.4 standard.
