摘要: A space-time signal processing system with advantageously reduced complexity. The system may take advantage of multiple transmitter antenna elements and/or multiple receiver antenna elements, or multiple polarizations of a single transmitter antenna element and/or single receiver antenna element. The system is not restricted to wireless contexts and may exploit any channel having multiple inputs or multiple outputs and certain other characteristics. Multi-path effects in a transmission medium cause a multiplicative increase in capacity.

摘要: An ultrasonic welding assembly comprising a horn, an anvil and an anvil cover. The horn comprises a generally T-shaped flattening surface and a rail projecting forward of the flattening surface. The rail is shaped to serve as a dam for flowing thermoplastic zipper material during stomping of slider end stops. The horn further comprises a plurality of vertical energy directors designed to direct ultrasonic energy into the mass of zipper material and deflect flowing zipper material toward the dam. The horn further comprises first and second recesses located on opposite sides of a stem of the T-shaped flattening surface. The anvil cover overlies opposing portions of the anvil and comprises a T-shaped cutout. The T-shaped flattening surface of the horn fits in the T-shaped cutout of the anvil cover. The resulting zipper has slider end stops located at opposing ends. Each end stop comprises flattened zipper material having a plurality of spaced indentations, the indentations being formed by the energy directors during stomping. The zipper can be pre-heated prior to ultrasonic stomping. A flange of the zipper can be cooled by fluid during ultrasonic stomping of the zipper parts.

摘要: A medium access contention protocol that is highly beneficial in wireless networks and particularly in wireless networks that employ a fixed minimum burst size such as OFDM wireless networks. In one embodiment, a MAC protocol is a demand-assigned protocol that maximizes utilization of the bus medium (the allocated frequency spectrum.) Each data communication device (DCD) in the network communicates with a central access point (AP). Multiple DCDs may request access from the AP in the same request access (RA) burst. Each of the multiple DCDs transmits its access request to the AP within a frequency domain channel in the RA burst that is orthogonal to the frequency domain channels used by the other DCDs requesting access. Each DCD includes channel training information in the access request burst to allow the AP and/or DCD to adapt to rapid variations in channel characteristics.

摘要: Method and apparatus for combining high data rate traffic and low data rate traffic on a common transmission medium while maximizing efficient use of available spectrum. Since spectrum is an economically valuable resource and transport of data generates revenue, the present invention directly leads to more profitable network operation. The disclosed systems are applicable to both wired and wireless transmission media. In one embodiment, a bandwidth reservation scheme provides that data rate may be varied so that when a particular data communication device is allocated a frame, it is also assigned a data rate for use in that frame. Because bandwidth usage varies with data rate, the division of available spectrum into channels for use by individual data communication devices may also vary among frames.
