Embodiments disclosed herein relate to improving a power output of a transmitter of an electronic device. To do so, the transmitter may include signal selection circuitry to adjust a sign selection signal to accurately transition between polarities of a quadrature (e.g., I or Q) component signal stored in or for which an indication is stored in a storage cell of a radio frequency digital-to-analog converter. The sign selection signal may generate a separate adjusted sign selection signal for each polarity of each quadrature component signal such that a transition of the selection signal between a first value and a second value (e.g., logic high and low) occurs when the respective quadrature (e.g., +/− and I/Q) component signal is a logic low. In this way, the signal selection circuitry reduces an error pulse in the output of the transmitter.

A memory controller having a data receiver to sample data at a sample timing using a strobe signal, wherein the data and the strobe signal are sent by a memory device in connection with a read operation initiated by the memory controller, and a strobe receiver to receive the strobe signal, wherein a phase of the strobe signal has a drift relative to a reference by an amount. The memory controller further having a monitoring circuit to monitor the strobe signal and determine the amount of the drift, and an adjustment circuit to update the sample timing of the data receiver based on the amount of drift determined by the monitoring signal.

Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.

A multi-chip module (MCM) includes a first integrated circuit (IC) chip to receive first data. The first IC chip includes a first transfer interface to transmit the first data off the first IC chip. A second IC chip includes an input interface to receive the first data from the first IC chip. The second IC chip includes switching circuitry to selectively forward the first data to one of a first output interface or a second output interface. The first output interface is communicatively coupled to a third IC chip, while the second output interface is configured to output the first data from the MCM.

Various example embodiments relate to partial data transmission. A transmitter may receive at least one dataset for transmission. The dataset may be one of a plurality of datasets known to the transmitter and a receiver or to be signaled to the receiver. The transmitter may determine a first portion of the dataset. The size of the first portion may be determined based on a battery level indicator, a latency level associated with the dataset, a radio condition, or a network load. The receiver may recognize the dataset based on the first portion and/or at least one second portion transmitted by the transmitter. Apparatuses, methods, and computer programs are disclosed.

In a case where signals branched from a single reference signal source are transmitted via a plurality of cables, a phase synchronization circuit can be used to stabilize a phase of a signal to be outputted from each cable. However, the phases of signal to be outputted from each cable is affected by combination of a length of each cable and an amount of delay caused by feedback control, so that phases of synchronization signals to be outputted from a plurality of transmission paths are not always the same as each other. In the present invention, since a frequency multiplier that multiplies a frequency of a signal outputted from each transmission path by an even number is provided for a phase synchronization circuit, the phases of the synchronization signals to be outputted from the transmission paths are aligned even when signals are branched from one reference signal.

A communication method, device, and a storage medium to resolve a problem that information about a clock frequency and a clock phase of a service cannot be correctly transmitted to a receiver or correctly recovered because transparent transmission of the information about the clock frequency and the clock phase of the service cannot be implemented. Because a value of k based on a reference data unit is inserted into a second data flow, and the value of k can indicate a quantity of third data units included between a second data unit and the reference data unit in a first data flow, a receive end device can completely recover the first data flow based on the value of k.

A method for synchronizing networks is disclosed. A first wired communication system having a first time base is set up in a first network. A second wired communication system having a second time base is set up in a second network. The first network and the second network are connected to a wireless communication system via a first translation unit and a second translation unit, respectively. The first translation unit and the second translation unit are synchronized to one another according to a third time base of the wireless communication system independently of the first time base and the second time base. A third synchronization message is transmitted from the first translation unit to the second translation unit. A transmission time for the third synchronization message in the third time base is determined and is used to synchronize the second time base to the first time base.

A clock recovery circuit may include a first circuit to produce an output signal that is a logical combination of an edge detection signal and a clock signal. At least some transitions in the edge detection signal may correspond to transitions in a set of data signals. The clock recovery circuit may also include a second circuit to average the output signal to produce a voltage, and a third circuit to add a variable delay to the clock signal based on the voltage.
