摘要： A free space communications apparatus includes a first receiving element configured to receive a communication signal and an ambient noise signal and to generate a first current as a function of any and all received signals, a second receiving element electrically coupled with the first receiving element to receive the ambient noise signal and to generate a second current as a function of any and all received signals, and an output signal produced as a function of the communication signal received by the first receiving element. The first and second receiving elements are electrically connected in a circuit that cancels at least a portion of the first current as a function of the second current to produce the output signal.
