    Abstract: A communication apparatus and a communication method are provided. The communication apparatus includes an antenna configured to receive a wireless signal, an oscillator driven by a driving current and configured to generate an oscillating signal based on the wireless signal, a measurer configured to measure an oscillation degree of the oscillating signal, and an accumulator configured to accumulate a difference between a target value and a measurement value of the oscillation degree. A value of the wireless signal is determined based on a cumulative signal corresponding to the accumulated difference.
