Abstract: A system and method of adaptively correcting the excitation or receive coefficients for a phased array antenna. For a transmitting antenna, a sensor located in the near field of the antenna is used to sense the antenna transmission. A reference signal that represents the sensor response to a desired antenna transmission that is accomplished with predetermined excitation coefficients is determined. The magnitudes and phases of the excitation coefficients are modified in a predetermined manner to create a modified antenna transmission. An actual signal that represents the sensor response to the modified antenna transmission is then determined. The excitation coefficients are then corrected using the differences between the reference signal and the actual signal, such that the modified antenna transmission becomes closer to the desired antenna transmission. The method and system also apply to a receiving antenna.

Abstract: A ping-pong scheme is used to slow down data transfer speed between an analog slicer in a receiver and a digital physical layer device, while maintaining the same data throughout. Two edges of a clock are used to slice the incoming analog signal, convert the analog signal to a digital signal and latch the converted signal. A ping-pong data pipeline is provided from the analog slicer to the physical layer device.

Abstract: The invention provides a method and apparatus for communicating to a destination node over a broadband network from plural users connected to an access node. A virtual circuit is provisioned through the broadband network for connecting the access node to the destination node. Data units are received from plural users at the access node, with each data unit having plural cells. The data units are multiplexed onto the virtual circuit at the access node such that the cells of any one data unit are noninterleaving with the cells of any other data unit on the virtual circuit. In a preferred embodiment, the destination node is a service provider node in an ATM network and the data units are Ethernet protocol data units that comprise plural ATM cells.

Abstract: A Scalable Multimedia Network providing integrated networking of data, voice, video and image services over a variety of access facilities including metallic loops, fiber/coax or digital fiber is disclosed herein. The SMN establishes customer initiated switched virtual circuits for all traffic types and directs them to the appropriate backbone network. The SMN is based on a distributed switching platform that includes a protocol adaptation capability which permits communications between customer premises equipment and potentially incompatible backbone networks or network servers.

Abstract: A Scalable Multimedia Network providing integrated networking of data, voice, video and image services over a variety of access facilities including metallic loops, fiber/coax or digital fiber is disclosed herein. The SMN provides a broadcast switch using a tiered system of buses. Channel units are made to interface to a bus of any tier depending on bandwidth requirements of the particular channel units. The SMN is based on a distributed switching platform that enables carriers to economically provide service to a small number of customers and add capacity incrementally as the customer base increases. The platform has a protocol adaptation capability which permits communications between customer premises equipment and potentially incompatible backbone networks or network servers.
