Abstract: A signal receiving apparatus and method are provided. When a baseband signal is restored, an orthogonal polarization state of light does not need to be precisely controlled. This is easy to implement and can reduce system costs. The apparatus includes an optical splitter configured to split a first polarization multiplexing optical signal into at least two second polarization multiplexing optical signals, and input the two second polarization multiplexing optical signals into at least two optical signal processing modules. An optical signal processing module is configured to couple the second polarization multiplexing optical signal, and input a coupled optical signal to a photoelectric detector configured to convert the coupled optical signal into an analog signal. An analog-to-digital converter is configured to convert the analog signal into a digital signal, and input the digital signal to a digital signal processor configured to process the digital signal to obtain a baseband signal.

Abstract: Embodiments are provided for a location-based network discovery and connection establishment, which take advantage of location/positioning technology of user equipment (UE) and resolve issues above of the blind search approaches. The location-based network discovery and connection establishment schemes use UE location information and a network access MAP to speed up network discovery, and remove the need for continuous search and measurement by the UE. The schemes also reduce the search space. A wireless network access map (MAP) is provided to the UE. The UE uses the MAP information with UE current location information to reduce the search space and speed up network discovery and radio connection establishment with the network. Network operators can use this network access MAP to control the network access and manage the network load distribution. The network access MAP can be customized for each UE.
