Abstract
A detector for detecting a traffic signal from a first demodulated signal is provided. The detector comprises a first stage for receiving the first demodulated signal and generating a first estimate of the traffic signal and a second stage connected to the first stage. The second stage receives the first demodulated signal and the first estimate of the traffic signal and generates a second estimate of the traffic signal from the first demodulated signal and the first estimate of the traffic signal. A method of detecting a traffic signal from a first demodulated signal is provided. The method comprises the steps of (a) generating an estimate of the traffic signal from the first demodulated signal using a first stage and (b) generating another estimate of the traffic signal from the first demodulated signal and the estimate of the traffic signal obtained from step (a) using a second stage.
