    Abstract: A data communication system includes a master and a slave. The master transmits a first subject signal including a first subject data to the slave via a transmission line. The slave extracts a clock signal from the first subject signal by performing a clock data recovery process and determines the first subject data based on the first subject signal. The slave transmits a second subject signal including a second subject data to the master during an existing period of the first subject signal without interfering an extracting of the clock signal and a determination of the first subject data. The master receives the second subject signal and cancels a waveform component of the first subject signal from a waveform of the second subject signal, and then determines the second subject data based on the second subject signal.

    Abstract: In a particular implementation, a method includes dynamically adjusting a size of a buffer of a receiving terminal based on a comparison of a signal quality metric associated with a wireless communication channel between the receiving terminal and a transmitting terminal to a signal quality threshold. The method also includes storing a first set of data packets of a plurality of data packets in the buffer. The first set of data packets are received at the receiving terminal from the transmitting terminal. The method further includes outputting reconstructed speech based on the first set of data packets and replacement packets that are generated based at least in part on the first set of data packets. The replacement packets are associated with a set of unreceived data packets of the plurality of data packets.

    Abstract: A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.

    Abstract: A host device, coupled to a slave device through a bus interface, includes a frequency detector, a jitter detector, and a signal processing circuit. The frequency detector receives a first work frequency, and determines whether the first work frequency is the same as a second work frequency of the slave device. The jitter detector receives a first clock signal, and determines whether a jitter difference corresponding to the first clock signal exceeds a predetermined range. The signal processing unit includes a clock signal input pin, a data input pin, and an output pin. When the first work frequency is the same as the second work frequency, and the jitter difference is within the predetermined range, the signal processing circuit outputs a data signal to the slave device according to the first clock signal, data and Seems System Management Bus protocol.

    Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. Previously, the instantaneous jitter was derived from a weighted history of the media stream, and consequently only packets that had already been received were used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.
