摘要： Disclosed is a method of distributing a number of reference clocks across a packet network. The packet network has a master node and one or more slave nodes, the master node and each slave node having basis clocks. A sender sends time-stamped synchronization packets to said one or more slave nodes, and a receiver at the slave nodes receives the time-stamped synchronization packets and synchronizes the basis clocks in the slave nodes with the basis clock in the master node. Multiple reference clocks are encoded with respect to the basis clock in the master node to generate numerical information describing the reference clock(s) in relation to the basis clock in the master node. The basis clock in each of the slave node is synchronized to the basis clock in the master node using time-stamped synchronization packets. The one or more reference clocks are recovered at the slave nodes using said numerical information describing the reference clock(s) in relation to the basis clock in the master node.

摘要： Disclosed herein is a relay service method for voice notice and a computer system for executing the same. In the present invention, a relay service company receives basic data for ARS voice notice from a user company, converts the basic data into a standardized markup language format, and transmits the markup language data to a communication network company, and the communication network company interprets the transmitted markup language data using a markup language interpreter, calls a customer, and executes a scenario. Accordingly, the various functions of a markup language can be utilized, high costs required for user companies to construct ARS voice notice systems, respectively, can be reduced, and a constructed ARS voice notice system can be utilized effectively.

摘要： Techniques for using protocol-enabled switches to provide time synchronization across store-and forward communication devices. A protocol-enabled switch according to the present techniques bypasses a store-and forward communication device for the purposes of time synchronization by merging timing packets into each subnet serviced by the store-and forward communication device, thereby avoiding the variable delays that may occur in the store-and forward communication device.

摘要： A communication system includes a transmitter and a receiver. The transmitter transmits a signal encoded by a low-density parity-check (LDPC) coding. The receiver includes a decoder, a phase error estimator, and a correction unit. The decoder decodes the signal at a plurality of sampling points using a single iteration of sum-product decoding. The phase error estimator estimates a phase error of the signal using minimum mean square error (MMSE) estimation and soft decision information obtained by the sum-product decoding. The correction unit corrects the signal using the phase error.

摘要： Remote units within a first communication system (121) utilizes frequencies (channels) from a second communication system (120) when placing a call. When a first remote unit (106) wants to call a second remote unit (107) using the channels, the first remote unit sends a base station (103) a list of top N traffic channel blocks from the second communication system along with the identity of the second remote unit. The base station then pages the second remote unit using a signaling channel reserved by second system. The second remote unit responds to the page with its list of best traffic channel blocks/chunks. The base station then picks the best overlap of idle channels from the list received by the remote units, and sends the list to the remote units instructing them use those traffic channels. Once the remote units receive the available channels, they can begin their call.

摘要： A method for processing an incident pulsed signal of an ultra wide band type received over a channel by a data device operating in a wireless data communications system is provided. The incident pulsed signal carries information within a super-frame structure. Upon reception of each super-frame structure by a data device, coarse synchronization is performed with another data device acting as a coordinator device for the wireless data communications system. The coarse synchronization uses a first training sequence. Upon reception of each frame allocated to the data device operating within the super-frame structure, channel estimation is performed using a second training sequence. The channel estimation also performs a frame synchronization.

摘要： A system and method that allows a user to concurrently connect to multiple wireless networks with a single network interface card is presented. The networks may be infrastructure (nullISnull) networks and ad hoc (nullAHnull) networks. A driver is inserted into a device's networking stack and exposes a plurality of virtual wireless network adapters, one for each network. The adapters are enabled and disabled in accordance with which network is presently activated. Packets for a network are queued when the network is not enabled. The wireless driver controls the switching of the network card. In one embodiment where multiple wireless cards are switching in and out of AH networks, the method converges the switching times for the cards in an AH network to ensure concurrent connectivity in the AH network for at least a brief time period every switching cycle of the wireless cards.

摘要： The invention concerns a method for transmitting large volumes of data via an asynchronous interface in a redundancy circuit of the checker-master type. The invention is characterized in that the data are transmitted on the basis of the type and volume of data to be transmitted, in accordance with different transmission cycles, whereof the operation is fixed and provided by means of finite state automatons (FSM) on both sides of the interface. Said FSM can control the management of the data on data buses whereof the number and size are random. On each of said buses, the data are stably maintained on the output side until they can be securely managed on the input side. Said concept enable transmission of a random number of data at every following phase until the cycle is completed.
