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