摘要： Multipath components of signals transmitted through time-varying digital radio channels are received with individual delays, and signals through a given channel comprise a code identifying that channel. A delay profile indicating a magnitude (Y) for delay values in a search window is calculated repetitively for known channels; the delays of multipath components for known channels estimated; a signal strength indicator calculated; and a search for new multipath components not already estimated performed at regular time intervals. When a new multipath component is found, its identification code is compared to the codes of the known channels. If the code of the new component is identical to the code of a known channel, a delay profile and a signal strength indicator is calculated for a window transposed to include the new multipath component. In this way as many multipath components as possible are included in the search window for a new cell.

摘要： The present invention relates to a distributed data storage system comprising a plurality of storage nodes. Using unicast and multicast transmission, a server application may write data in the storage system. When writing data, at least two storage nodes are selected based in part on a randomized function, which ensures that data is sufficiently spread to provide efficient and reliable replication of data in case a storage node malfunctions.

摘要： A method for maintaining a data storage system is disclosed. The method may include monitoring for receipt of a first broadcast message from a first data storage node, where the first broadcast message may indicate that the first data storage node is operating correctly. The method may also include detecting that the first data storage node is malfunctioning based on not receiving the first broadcast message for a predetermined period of time. The method may also include initiating a data replication procedure based on detecting that the first data storage node is malfunctioning. The data replication procedure may include sending a first multicast message to a plurality of data storage nodes requesting identification of a second data storage node that maintains a copy of a file stored on the first data storage node.

The method may include sending a multicast message to at least a subset of the storage nodes. The multicast message may include a request for the subset of storage nodes to send the data. The multicast message may further include a data identifier, indicating the data to be retrieved. Moreover, the method may include receiving data from a first storage node of the subset of storage nodes. The data received from the first storage node may correspond to the requested data. At least the act of sending a multicast message or the act of receiving data from the first storage node may be performed on a condition that an estimated size of the data is less than a predetermined value.
