The disclosed couplers operate in a “near field” mode, meaning energy, whether used to transmit data or power, is transferred through magnetic induction using a ∂i/∂t circuit (meaning a change in current over a change in time), such as by using inductive transmission and receive coils in which resistors and/or other components such as diodes are placed into series and/or in parallel with the coils and used to control the shape of the pulse, e.g. its voltage and/or frequency. In embodiments, the connectors are use to couple a power source to a power receptor.

The present invention is directed to data communication. More specifically, embodiments of the present invention provide a transceiver that processes an incoming data stream and generates a recovered clock signal based on the incoming data stream. The transceiver includes a voltage gain amplifier that also performs equalization and provides a driving signal to track and hold circuits that hold the incoming data stream, which is stored by shift and holder buffer circuits. Analog to digital conversion is then performed on the buffer data by a plurality of ADC circuits. Various DSP functions are then performed over the converted data. The converted data are then encoded and transmitted in a PAM format. There are other embodiments as well.

A method includes: receiving, by a BBU, M groups of signals, where each group of signals includes N signals, M is an integer greater than 0, and N is a maximum quantity of signals supported when a physical cell of the BBU demodulates a signal; determining, by the BBU, H groups of signals that carry data and that are in the M groups of signals, where 0<H≤M; combining, by the BBU, the H groups of signals into one group of data; and demodulating, by the BBU, the combined group of data.

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.

Based on the NSSS transmit diversity scheme, at least one measurement is performed across NSSS occasions.

A system for providing a residential IP network includes a plurality of transceiver circuitries, each associated with a building, for transmitting signals to/from the associated building. An optical network unit transmits and receives signals at a first frequency with an optical network. A remote unit integrated with the optical network unit converts the received signals at the first frequency into a first format that overcome losses caused by penetrating into the interior of the building over a wireless communications link and transmits the signals in the first format using beam forming and beam steering to provide the wireless signals to at least one of the plurality of transceiver circuitries. Each of the plurality of transceiver circuitries further includes first circuitry, located on an exterior of the building, for transmitting and receiving the signals in the first format. A first antenna associated with the first circuitry for transmits the signals in the first format into the interior of the building via a wireless communications link and receives signals from the interior of the building in the first format via the wireless communications link. Second circuitry, located on the interior of the building and communicatively linked with the first circuitry via the wireless communications link, receives and transmits the converted received signals in the first format that counteracts the losses caused by penetrating into the interior of the building from/to the first circuitry. A second antenna associated with the second circuitry transmits the signals in the first format to the exterior of the building via the wireless communications link and receives signals from the exterior of the building in the first format via the wireless communications link.
