摘要： A system and method for facilitating user communication from a location. The system comprises two or more cameras for capturing two or more videos at a first location, a control unit for streaming one or more of the videos captured to a first communication unit at the first location through a first network, and streaming one or more of the videos captured to a second communication unit located at a second location through a second network, a server for identifying a location data of the first location based on an identifier of the control unit, and a communication platform associated with the first location. The communication platform is accessible by the first and second communication units through the first and second networks respectively. The communication platform comprises a first display for displaying one or more of the videos captured, a second display for displaying the location data of the first location identified by the server, and one or more control interfaces for controlling the camera view of the one or more videos displayed in the first display, wherein controlling the camera view comprises switching the one or more videos displayed in the first display between videos captured by the two or more cameras.

摘要： An architecture for a receiver component in a wireless communications system is disclosed—one that supports both zero intermediate frequency (ZIF) and near-zero intermediate frequency (NZIF) operation. The architecture provides a down-conversion segment, and a local oscillator segment operatively associated with the down-conversion segment. An analog-to-digital conversion (ADC) segment is adapted to receive signals from the down-conversion segment and introduce the signals into a digital intermediate frequency (DIF) construct. The DIF construct performs a DC offset compensation or DC residue filtering on NZIF-based signals, and droop or mismatch compensation. Image removal is performed on NZIF-based signals, and DC offset compensation is performed on ZIF-based signals. Compensated signals are amplified to some nominal or desired level, and interpolation filtering of the amplified signals is performed prior to transmission thereof.
