Abstract: A Bluetooth Low Energy (BLE) device, having a demodulator configured to translate in-phase and quadrature components of a received BLE signal into a differential phase signal; an estimator configured to estimate a frequency offset of the differential phase signal; and a detector configured to detect information in the differential phase signal corrected by the estimated frequency offset.
