Abstract:
A method of feedforward phase recovery on a data stream is described. Phase estimation base points are calculated, at a phase detector, for each block of the received data stream. A current phase, at a phase interpolator, between two phase estimation base points. Data stream delays within the phase detector are matched with delays within the phase interpolator.
Abstract:
Method and apparatus for iterative timing recovery for FTN signaling are provided. The iterative timing recovery method and apparatus uses a feedback timing error signal from a forward error correction block with an additional equalizer prior to a maximum a posteriori (MAP) decoder which matches the equalized FTN signal to a truncated inter-symbol interference (ISI) target. A timing error is then generated using a modified M&M timing error detector.
Abstract:
A method of detecting and correcting cycle slip in a data stream including sync symbol blocks and data symbol blocks prior to feedback carrier recovery is described. A phase ambiguity angle is computed upon detecting a last sync symbol of a sync symbol block in the data stream. A cycle slip corrector initiates cycle slip correction upon determining the computed phase ambiguity angle is different from a previous computed phase ambiguity angle to generate a corrected data stream. The corrected data stream is provided to a feedback carrier recovery circuit.
Abstract:
The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and a process for the preparation of a hardening accelerator composition by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction of the water-soluble calcium compound with the water-soluble silicate compound being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders. The invention concerns also a composition of calcium silicate hydrate and comb polymer, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.

Abstract:
A method of frame sync detection is described. A first and second differential correlation of a data stream is calculated, at a plurality of delay and conjugate multipliers. The first and second differential correlations are convolved with a previous set of differential correlations. A correlation peak is calculated, at a sync detector, using the convolved differential correlations, to detect a frame sync.
