Abstract
The present application relates to a near field communications (NFC) receiver in which a received NFC signal comprising a carrier signal onto which a data signal is modulated is digitised and downconverted, and the digitised and downconverted received signal is filtered to recover a digitised and downconverted version of the carrier signal of the NFC signal. This digitised and downconverted version of the carrier signal is converted into an analogue signal which is then upconverted to generate an estimate of the carrier signal, and this estimate is combined with the received NFC signal to suppress or negate, at least partially, the carrier of the received signal.
