Abstract

A receiver for receiving an RF signal transmitting a bit sequence representing a symbol is provided. The receiver includes an oscillator, a counter, at least one state machine and at least one correlator. The oscillator is configured to oscillate dependent on the received RF signal, wherein the oscillator signal is controlled to provide an oscillation signal based on the oscillation during a plurality of subsequent active periods. The counter is configured to provide a counter value describing threshold crossings of the oscillator signal for each of the active periods. The at least one state machine is connected to the counter and configured to output state values, each state value dependent on two subsequent counter values. The at least one correlator is configured to correlate the output state values with a predefined bit sequence and to output a value representing the symbol dependent on the correlation.
