While these wireless networks must use signal powers as low as possible so that they will not adversely affect human bodies, they must be reliable in noisy and physically-complex indoor environments. Consumer wireless networks therefore need to use new and better error-correction techniques. Previous error-correction techniques concerned both coding and decoding. Research in coding gave us the BCH and Reed-Solomon codes, extending the correction limitation (the number of correctable bit errors). Research in decoding explored ways of recovering more bit errors. This work proposes a new decoding method suitable for consumer wireless networks, one that can recover roughly 40% more errors than the current correction limitation.","PeriodicalId":101716,"journal":{"name":"2005 Digest of Technical Papers.

The investigated SLM scheme selects the transmitted sequence with the lowest average PAR over all transmitting antennas and retrieves the side information very accurately at the expense of a slight degradation of the PAR performance. The low probability of false side information can improve the overall detection performance of the MIMO-WLAN system with erroneous side information compared to the conventional SLM approaches, respectively.","PeriodicalId":101716,"journal":{"name":"2005 Digest of Technical Papers.

Under undetermined network traffic and ambiguous user QoS requirements, a well-designed multimedia QoS system should adapt the resource reservation request according to the user QoS requirements and the network resource status. The paper proposes a user-oriented QoS streaming system (QOs and user-oriented, Qoo) to achieve user-level perceivable satisfaction based on the novel streaming and media differentiation policies. The Qoo system provides a user-oriented dynamic QoS specification and mapping (UDQSM) system to achieve QoS specification and mapping adaptively at the application layer. A user-friendly interface for QoS parameter authoring is designed in the UDQSM system. We propose a dynamic QoS queue mapping (DQ/sup 2/M) algorithm for QoS differentiation, and, to avoid the inefficient resource utilization originating from that, a popular service queue suffers congestion and the other queues are in the starvation state.","PeriodicalId":101716,"journal":{"name":"2005 Digest of Technical Papers.
