  • Publication number: 20120281784
    Abstract: The present invention relates to signal processing in an analog-to-digital converter comprising a time-interleaved multi-channel architecture. According to the invention: digital filtering (H(z)) is applied in each channel, at least to estimate a converter offset error, and a compensation for the offset is applied on the basis of the estimated offset error. Advantageously, it is possible to benefit from the presence of a digital filter (H(z)) that is usually used to filter the quantization noise, such as a comb filter in converters that have sigma/delta modulators, in order to estimate the offset. The same filtering can then be applied in order to also estimate a gain disparity between the different channels.

  • Publication number: 20080071900
    Abstract: A method of managing a communication network comprising a control plane and a network plane, the network comprising nodes and physical connections of the nodes, each of a plurality of nodes being a logical network device, supporting a control plane portion in the control plane and a network plane portion in the network plane, in which method, the control plane portions of the logical network devices form a logical network in a peer to peer fashion, and control data necessary for administering the communication network and/or for managing users of the communication network is contained in at least one database distributed between at least a plurality of control plane portions of the network devices forming the logical network.
