摘要： In an orthogonal frequency division multiplex (OFDM) communication network, a node transmits an echo profile probe to other nodes in the network. The echo profile probe is a message that allows characterization of the unique echo profile through the communication channel between each node pair. The echo profile is used to calculate the cyclic prefix length needed for optimum communication from one node to the other.

摘要： Methods and apparatus for communicating unicast PQoS DFID information in a MoCA network are disclosed. In a transmitting apparatus, values are assigned in a first set of fields of a reservation request element, the first set adapted to indicate a unicast PQoS flow with a DFID value. Values are assigned in a second set of fields of the reservation request element, the second set adapted to represent the DFID value. A message comprising the reservation request element is transmitted to a network coordinator. In a receiving network coordinator, a message comprising a reservation request element is received, the reservation request element comprising a first set of fields and a second set of fields. It is determined whether the first set is indicative of a unicast PQoS flow with a DFID value. The DFID value is determined from the second set if the first set is indicative of a unicast PQoS flow with a DFID value.

摘要： Several local IEEE1394 buses are bridged together over a second bus type to create a global bus wherein each local bus node is able to address nodes across the global bus without the local nodes being aware of the bridging operation. A bridging device operates by translating local bus node addresses to a global bus for communication over the second bus type. Alternatively, the local bus node identification process is controlled by the bridging device operating as the root node to cause the local nodes to be identified with a node address that is unique for the global network. The second bus type operates as a backbone for the global network and can be any type of communication bus or network with capability to transport the local bus traffic. The bridging devices that interface the local IEEE1394 buses to the backbone contain portals specific to each bus type that can communicate data between the dissimilar buses.

摘要： Multiple channels of received data are processed by a multiple channel demodulation and error correction decoding engine. The statistical uncertainty of processing channels with an iterative decoder are averaged across all the channels to reduce the total processing power required of the decoding engine compared to processing each channel with a separate engine. A set of input buffers holds blocks of data for each channel needing decoding. A quality measure is computed on each input block to set the priority and iteration allocation of decoding in the common decoder. The input RF signal is digitized by a broadband tuner that processes some or all of the channels to feed the multiple channel demodulator and decoder. Multiple decoded video data streams are output.

摘要： Various systems and methods are provided for channel estimation. These systems and methods (a) determine a coherence bandwidth for the channel, (b) adapt the channel estimation based on the coherence bandwidth, and (c) perform channel estimation by transmitting a channel estimation symbol over a channel. In some embodiments, the channel estimation is adapted based on the coherence bandwidth. This may include selecting a number of channel estimation symbols to transmit in a packet. Additionally, the number of channel estimation symbols transmitted in a packet can be selected by increasing the number of channel estimation symbols when the coherence bandwidth of the channel is high or decreasing the number of channel estimation symbols when the coherence bandwidth of the channel is low.

摘要： According to some embodiments of the disclosed method and apparatus, systems and methods are provided that utilize extra payload capacity present in a symbol pad of a PHY payload to decrease the coding rate of an FEC coding scheme without increasing the symbol rate or decreasing the PHY rate of a corresponding data transmission. If a symbol pad length that would result from encoding a MAC frame using a default coding scheme would be at least as great as a parity length of the default coding scheme, and a new coding scheme maintaining the same parity length but having a reduced information bit length may be determined and used to encode the MAC frame. Owing the reduced information bit length, the new coding scheme has a reduced coding rate, but maintains the same number of OFDM symbols as the default coding scheme.
