Abstract
The determination of a Rician signal envelope in low signal/noise is a biased estimate of the true (noiseless) envelope. Four statistical estimators which attempt to correct for the biasing are investigated, namely the maximum likelihood, most probable, mean and median estimators. Confidence intervals on the envelope estimation are also presented at the 68%, 95% and 99% confidence levels.
