摘要： The object of the invention is to provide a simplified QoS guarantee in bidirectional point-to-multipoint access networks, such as LMDS. This object is attained by a QoS controller containing at least one software module which is adapted to perform at least one QoS processing step for both the uplink and the downlink. In the case of the QoS controller according to the invention, the same QoS controller and the same software module are used for at least a major part of the connection both in the uplink and the downlink. This has the advantage, inter alia, that a nearly symmetrical behavior is achieved for the uplink and downlink.

摘要： Determination of the location of an error condition or a failure includes receiving at a network interface a first framed digital signal from customer premises equipment, and determining whether the first framed digital signal indicates a failure. Overhead bits are modified in the first framed digital signal to generate a second framed digital signal, such that the modification is equivalent to insertion of errors into the first framed digital signal at a bit error ratio (BER) of not greater than a predetermined ratio, if the first framed digital signal indicates a failure. The second framed digital signal is then sent from the network interface in place of the first framed digital signal to indicate that the failure reported by the first framed digital signal is located in the customer premises equipment. Otherwise, if no failure is indicated, the first framed digital signal is transmitted without any modifications.

摘要： Apparatus, and an associated method, for selecting operational parameters pursuant to which a radio communication system is operable. The operational parameters form, for instance, adaptive switching thresholds used in an adaptive modulation scheme. Separate learning controllers are configured to operate independently and cooperatively to select the adaptive switching thresholds, or other operational parameters. Iterative operation of the learning controllers causes the values to converge to optimal values.

摘要： A wireless communication network with improved performance and a method and controller for controlling data rate in the network are provided. The invention provides a feedforward approach to data rate control in wireless networks. The invention is based on designing an optimal, but non-causal, controller and its subsequent nullcausification,null which results in a practical, implementable controller, driven by an estimate of the bit error probability. This controller leads to a minimum 5%-85% increase in average throughput without additional power utilization, as compared with fixed data rate operation.

摘要： The present invention provides a frame synchronization device for receiving frames and establishing frame synchronization. The frame synchronization device attempts to detect a first synchronization data in a received data in a frame hunting state, and enters a synchronous state when the first synchronization data is detected for a first predetermined number of consecutive frames. The device corrects errors of the data in the frame based on a check data in the frame. And the device attempts to detect a second synchronization data in the corrected frame, and returns to the frame hunting state when the second synchronization data is not detected.

摘要： Methods and apparatus for decoding codewords using message passing decoding techniques which are particularly well suited for use with low density parity check (LDPC) codes and long codewords are described. The described methods allow decoding graph structures which are largely comprised of multiple identical copies of a much smaller graph. Copies of the smaller graph are subject to a controlled permutation operation to create the larger graph structure. The same controlled permutations are directly implemented to support message passing between the replicated copies of the small graph. Messages corresponding to individual copies of the graph are stored in a memory and accessed in sets, one from each copy of the graph, using a SIMD read or write instruction. The graph permutation operation may be implemented by simply reordering messages, e.g., using a cyclic permutation operation, in each set of messages read out of a message memory so that the messages are passed to processing circuits corresponding to different copies of the small graph.
