Abstract
An optical and electrical hybrid beamforming transmitter, receiver, and signal processing method are provided. The transmitter includes, but is not limited to, two photoelectric converters, two adjusting circuits, and an antenna array. The photoelectric converter converts an optical signal into an initial electric signal, respectively. The adjusting circuit is coupled to the photoelectric converter, and are adapted for delaying the initial electric signal according to an expected beam pattern formed by the antenna array, respectively, to output an adjusted electric signal. The antenna array includes two antennas that are coupled to the adjusting circuit. The antenna radiates electromagnetic wave according to the adjusted electric signal. Accordingly, a phase of the signal may be adjusted, and the number of the elements may be reduced.
