Abstract: In digital communications that utilize a data packet format wherein each data packet includes a physical layer (PHY) component and a media access control layer (MAC) component, the media access control layer component can be selectively protected by forward error correction (FEC). The receiving end receives an indication as to whether FEC has been applied, and makes an FEC decision based (12-15) on this indication. The accuracy of the received-side FEC decision and the robustness of the FEC indication can be improved by: making the FEC decision based on the results of FEC decoding applied to a media access control layer header within the media access control layer component; providing an FEC indication bit in the physical layer component; and using a plurality of bits to encode the FEC indication in either the physical layer component or the media access control layer component.

Abstract: A method provides frequency and phase offset estimation in a SCDMA burst receiver (such as a DOCSIS 2.0 SCDMA burst receiver) by application of the known Least Square (LS) parameter estimation algorithm to a pre-known transmitted sequence, called preamble, in order to optimally characterize the phase and frequency offsets affecting the transmitted data. The LS parameter estimation algorithm is adapted to SCDMA burst receiver specifications by changing index calculations to fit according to SCDMA preamble locations. Improved estimation accuracy can be achieved by using weighted least squares that disregard symbols affected by impulse and burst noise. Weighted least squares can further impart more weight to last symbols to more accurately estimate contemporary impairments. The method is particularly useful for communication systems having large frequency and phase offsets as in the DOCSIS 2.0 SCDMA burst receiver.

In accordance with the present invention, a change indicator is initialized at the start of a monitoring period. Then, during the monitoring period, the stored parameters are monitored for changes in those of thee stored parameters that define the quality of service. When a change is detected, the change indicator is updated in response and other devices in the network are periodically notified of the current value of the change indicator. The other devices are operable to update locally stored quality of service parameters in response to detecting a change in the change indicator.
