Disclosed are systems, devices and methods for estimating blood glucose parameters, including blood glucose concentration glucose sensor signals. In some aspects, a method for estimating blood glucose concentration from signals of glucose sensors includes obtaining a set of time-series values that includes tissue glucose sensor values from a glucose sensor and reference blood glucose concentration values associated with a subject; generating a set of matched blood glucose reference values by determining a temporal matching of the tissue glucose sensor values and the reference blood glucose concentration values; isolating error associated with the matched blood glucose reference values to determine a residual error time series, wherein the isolated error includes a composite error comprising a measurement error, a process error, and random error; and producing estimated blood glucose values for true blood glucose of the subject by adding the reference blood glucose concentration values to the residual error time series.
