A signal generation method is used in a transmission device that transmits a plurality of transmission signals from a plurality of antennas at the same frequency and at the same time, in the case where larger power change is performed on a first transmission signal than on a second transmission signal during generation process of the first transmission signal and the second transmission signal, the first transmission signal and the second transmission signal are mapped before the power change such that a minimum Euclidian distance between possible signal points for the first signal is longer than a minimum Euclidian distance between possible signal points for the second signal.

A pixel for an image sensor includes a microbolometer sensor portion, a visible image sensor portion and an output path. The microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the microbolometer sensor portion. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the microbolometer and the visible image sensor portions, and is controlled to selectively output the signal corresponding to the IR image or the signal corresponding to the visible image. The output path may be further shared with a visible image sensor portion of an additional pixel, in which case the output path may be controlled to selectively to also output the signal corresponding to a visible image of the additional pixel.

A UE determines a first DCCH resource candidate in a first CORESET on a carrier, the first DCCH resource candidate including a first set of RBs. The UE also determines a first sequence of DMRSs that are mapped, starting at a reference point, to RBs in a predetermined range within the carrier in a frequency domain, the predetermined range containing the first DCCH resource candidate in the frequency domain. The UE further determines a first reference location of the first set of RBs. The UE determines, based on the first reference location, a first set of DMRSs from the first sequence of DMRSs, the first set of DMRSs being mapped to the first set of RBs. The UE obtains a channel estimation based on the first set of DMRSs; and The UE performs blind decoding of the first DCCH resource candidate based on the channel estimation.

An apparatus comprises an RF receiver for receiving an RF signal. The RF receiver includes front-end circuitry to generate a first down-converted signal, and a plurality of signal detectors to generate a corresponding plurality of detection signals from signals derived from the down-converted signal. The RF receiver further includes a controller to provide at least one control signal to the front-end circuitry based on the plurality of detection signals.

A method of transmitting a Physical Layer Convergence Procedure (PLCP) frame in a Very High Throughput (VHT) Wireless Local Area Network (WLAN) system includes generating a MAC Protocol Data Unit (MPDU) to be transmitted to a destination station (STA), generating a PLCP Protocol Data Unit (PPDU) by adding a PLCP header, including an L-SIG field containing control information for a legacy STA and a VHT-SIG field containing control information for a VHT STA, to the MPDU, and transmitting the PPDU to the destination STA. A constellation applied to some of Orthogonal Frequency Division Multiplex (OFDM) symbols of the VHT-SIG field is obtained by rotating a constellation applied to an OFDM symbol of the L-SIG field.

Systems and apparatuses for wireless power transfer system are described. A receiver may send an amplitude shift key (ASK) signal to a transmitter. The transmitter may receive the ASK signal from the receiver. The transmitter may perform a demodulation on the ASK signal. The transmitter may, in response to a failure to demodulate the ASK signal, encode a notification of failure in a frequency shift key (FSK) signal. The transmitter may transmit the FSK signal to the receiver. The receiver may receive the FSK signal. The receiver may perform a function to resolve the failure to demodulate the ASK signal.

An apparatus (7) for down-converting a sampled signal comprises a processing system (206) configured to apply a mixing-and-combining operation repeatedly to successive sub-sequences of N input samples, X, representative of a signal and having an initial sampling rate, M, to generate a sequence of output samples, Y, having an output rate, T, lower than the initial sampling rate M. The sub-sequences of the N input samples, X, are spaced at intervals that correspond to the output rate M. The mixing-and-combining operation generates a respective output sample Y from each sub-sequence, where Y depends on a set of products of the input samples X of the sub-sequence with respective values derived from a periodic mixing signal having a mixing frequency.
