Abstract: A signal receiving circuit amplifies a radio frequency signal by using a first radio frequency amplifier, and outputs a first amplified signal in a same phase; amplifies the radio frequency signal by using a second radio frequency amplifier, and outputs a second amplified signal at an inverse phase. A first mixer mixes a first local oscillator signal with the first amplified signal to obtain a first frequency mixing signal; a second mixer mix a second local oscillator signal with the second amplified signal to obtain a second frequency mixing signal, where a phase of the first local oscillator signal is opposite to a phase of the second local oscillator signal; and after adding the first frequency mixing signal and the second frequency mixing signal, an output interface outputs the first frequency mixing signal and the second frequency mixing signal.

Abstract: The present disclosure relates to optical wireless communication methods and devices. In one example method, a first communication device receives optical signals separately transmitted by N nodes, and obtains, based on the received optical signals of the N nodes, first parameters that are of the N nodes and that are used to locate the first communication device and an information bit stream corresponding to each node. The optical signals are obtained by the nodes by performing electrical-to-optical conversion on a first signal, the first signal is a signal obtained by adding a direct current bias signal to a second signal, and the second signal is a signal obtained after constant envelope modulation is performed on an information bit stream to be sent by a light source node to the first communication device.
