摘要： A desired signal having a wide frequency band and including sequential symbols representing digital values is discriminated from a narrow band interfering signal having a carrier frequency in the wide band by initially applying both signals to a filter so both signals are passed to an output of the filter. In response to the filter output, estimates of the values of received symbols of the desired signal are derived and compared to the filter output to derive an error representing signal. A characteristic of the filter is controlled in response to the error representing signal so the filter is adjusted to reject the interfering signal and pass the desired signal.

摘要： A finite field parallel multiplier in GF(q.sup.m) including a router for directing 2m-1 components in m groups of m single-component signal lines towards m computing circuits for performing multiply and add modulo-q. The router guides m components from a first finite field element along with an additional m-1 components generated from linear combinations of the m components of the first finite field element. Each of the computing circuits receives all of the components from the second finite field element and m components provided by one set of signal lines through the router. Each computing circuit generates a single component for the resultant finite field element. These resulting components may be input through a basis change circuit to obtain a result in the desired basis.

摘要： A programmable channel scanning and acquisition method for a cable modem first performs a fast scan and then a slow scan to identify channels supporting cable modem services. The fast scan involves only a check of the cable modem AGC lock. A list of potentially operational channels is assembled and scanned. The list includes, in order of preference, the last known good channel, golden channels that are likely to support cable modem services, “learned” golden channels consisting of previous last known good channels, and other channels within the frequency plan range. The list omits channels on a “black list” known not to be operational and channels outside of the frequency range, except during registration. The method may be optimized by the setting of various parameters for operation in a DOCSIS or EuroDOCSIS environment.

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.
