Signal processing for continuous analyte sensor

A system for compensating for a time lag of continuous analyte sensor data, the system comprising:

• an input module operatively connected to the continuous analyte sensor that receives sensor data, wherein the sensor data comprises a) a physiological time lag with respect to blood analyte data or reference analyte data, b) a membrane-induced time lag, and/or c) a computationally-induced time lag;
• and
• a processor module comprising programming configured to continuously and/or intermittently estimate one or more analyte values based on the sensor data including a first time lag compensation, evaluate analyte values compensated for the first time lag compensation with time-corresponding received anal e values to determine an updated time lag compensation associated with the sensor data and compensating analyte values based on the updated time lag compensation associated with the sensor data, wherein the processor module further comprises programming configured to continuously or intermittently provide an output based on the time-lag compensated estimated analyte values.
