    摘要: A transmitter is disclosed for transmitting a transmission signal via a transmission medium. The transmitter derives a prediction signal from the digital information signal in dependence on an array of prediction filter coefficients. The array of prediction filler coefficients is obtained by smoothing a first array of coefficients. Said first array of coefficients is generated in response to the digital information signal. A residual signal is obtained by combination of the digital information signal and the prediction signal. The residual signal is encoded so as to obtain an encoded signal. The encoded signal is transmitted via the transmission medium.

    摘要: A method and system for transmitting and receiving a signal between first and second mobile nodes is provided. The method and system offers improvements to the throughput of an overall wireless local area network. When the first mobile node receives a data frame from the second mobile node, third mobile nodes can also transmit and receive the data frame. The first mobile node sends an acknowledgement (ACK) frame for notifying that the data frame has been completely received to the second mobile node through a common channel.

    摘要: A method and apparatus in a packet-switched communication network for controlling Quality of Service (QoS) for a packet-switched data stream that includes a plurality of contiguous data packages. The network normally provides the data stream to users at a first QoS level. When it is determined that a receiving user is not authorized to receive the data stream at the first QoS level, the apparatus intercepts the data stream prior to receipt by the receiving user and extracts selected data packages from the data stream to reduce the QoS level for the data stream to a lower, second QoS level to match an authorization status of the receiving user. The apparatus then forwards to the receiving user, a modified data stream with the lower, second QoS level.
