摘要： A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.

摘要： A method of reducing transmission power for an encoded data stream includes the steps of receiving an incoming data stream having equal probability for a plurality of incoming data bits, assigning a symbol scheme to the received data bits of the incoming data stream according to probabilities of occurrence of individual ones of the received data bits, and transmitting an outgoing data stream according to the assigned symbol scheme having a second average transmit power, different than the first average transmit power, for a plurality of outgoing symbols.

摘要： A scheduling device for managing a packet queue of a communication gateway includes a receiving portion configured to receive data packets according to at least one communication protocol, a processor, and classification module configured to separate the received data packets into a first traffic queue and a second traffic queue separate from the first traffic queue. The first traffic queue includes a low latency service flow classified to have strict priority. The second traffic queue includes a primary service flow classified as having a classic priority.

摘要： A receiver is configured to capture a plurality of linearly distorted OFDM symbols transmitted over a signal path. The receiver forms the captured OFDM symbols into an overlapped compound data block that includes payload data and at least one pseudo-extension, processes the overlapped compound block with circular convolution in the time domain using an inverse channel response, or frequency domain equalization, to produce an equalized compound block, and discards end portions of the equalized block to produce a narrow equalized block. The end portion corresponds with the pseudo-extension, and the narrow block corresponds with the payload data. The receiver cascades multiple narrow equalized blocks to form a de-ghosted signal stream of OFDM symbols. The OFDM symbols may be OFDM or OFDMA, and may or may not include a cyclic prefix, which will have a different length from the pseudo-extension.

The first traffic queue includes a low latency service flow classified to have strict priority. The second traffic queue includes a primary service flow classified as having a classic priority. The classification module separates the received data packets so that those with a first indicator are sent to the first traffic queue and those without the first indicator are sent to the second traffic queue.
