Abstract
A wireless receiver () for receiving and demodulating a frequency modulated RF (radio frequency) signal by a direct conversion procedure, including channels () for producing in-phase and quadrature components of a received RF signal, and a processor () for periodically estimating an error in at least one of the in-phase and quadrature phase components and for producing a signal for adjustment of at least one of the in-phase and quadrature components to compensate for the detected error, wherein the processor is operable to apply alternatively each of a plurality of different procedures to estimate the error, the procedures including a first procedure which is applied when a signal quality value of the received RF signal is above a threshold value and a second procedure which is applied when a signal quality value of the RF received signal is not above the threshold value.
