Abstract: A remote satellite modem, in conjunction with a mediation device configuration propagates frames over a cellular backhaul link so as to preserve PRC traceability by receiving a frame based signal, in which the frame based signal conforms to a hub timing signal operable to demarcate frames in the frame based signal, and identifies a start of frame in the received frame based signal, such that the start of frame is independent of the symbol timing of the hub timing signal. In response to the start of frame, the modem generates a timing packet corresponding to a remote timing signal, and forwards the timing packet and the frame based signal, in which the timing packet is for decoding the frame based signal corresponding to the hub timing signal using the remote timing signal.

Abstract: A method and apparatus for selectively accelerating network communications provides improved operation of network communications through channels with long delays, such as a satellite communications channel. A configuration management mechanism provides a selection of acceleration configuration for particular addresses of devices that may communicate through the communications channels. Acceleration may be bypassed for particular addresses or classes of devices within the network and priorities may be assigned, permitting a cut-off of acceleration when a threshold number of sessions is reached. The method and system may also allow a higher priority class of session to preempt lower priority session by removing resources from the lower priority session and assigning them to the higher priority session. The data rate of the lower priority session is then lowered (due to the absence of acceleration or reduced buffer size) to reduce traffic flow.

Abstract: A digital Intermediate Frequency (IF) processing block including a decimation filter having Finite Impulse Response (FIR) decimation stages provides improved performance over a Hogenauer decimating filter. The filter comprises multiple integrator stages followed by multiple FIR decimating stages. The zeros of the filter are tunable by adjusting the integer coefficients of the FIR stages providing tunability of the cut-off response, as opposed to the fixed sinc response of the Hogenauer filter. As a result, the number of required stages for a particular steepness is reduced, dramatically reducing the amount of digital circuitry required to implement a particular filter design. The improved filter is especially suitable for use in digital IF stages in receivers, and for code-based applications where selectable decimation rate is desired and a fast multiply is not available.
