  • Patent number: 6360090
    Abstract: Disclosed is a method and apparatus for receiving infrared signals that is better able to receive a data signal in the presence of a noise signal. The method according to the present invention involves bandwidth filtering an incoming signal that includes a data signal and a noise signal. The bandwidth filtered signal is then averaged to obtain an average alternating current (AC) value signal of the bandwidth filtered signal. The average AC value signal is integrated to obtain a detect level adjustment signal. The detect level adjustment signal is summed with a minimum detect threshold value to obtain a detection level signal. The incoming signal is then compared to the detection level signal in order to produce a received data signal.
