Abstract: A method for extracting a plurality of data streams from a time-frequency division multiplexed (TFDM) signal includes determining a plurality of sub-channels of the TFDM signal, where each of the plurality of sub-channels has a respective one of a plurality of frequency ranges. The method also includes down-converting, based on the plurality of frequency ranges, the TFDM signal into a plurality of down-converted signals, where each down-converted signal corresponds to a respective one of the plurality of sub-channels. The method also includes extracting the plurality of data streams from a respective one of the plurality of down-converted signals.

Abstract: The disclosure is generally directed to systems and methods for controlling electrical power outlets in a vehicle. An example method executed by a processor of an electrical power outlet controller includes detecting a transitioning of a vehicle to a drive mode and further includes disconnecting, based on the transitioning, electrical power supplied to a first electrical power outlet in the vehicle. The transitioning of the vehicle to the drive mode may be detected based on a transition of a drive selector of the vehicle from a park position to a drive position. In another example method, the processor, detects the vehicle in motion and disconnects electrical power supplied to a second electrical power outlet in the vehicle. The first electrical power outlet and/or the second electrical power outlet are accessible from outside the vehicle, and may, for example, be located outside a cabin area of the vehicle.

Abstract: A method for performing downlink transmissions from a transmitting device to multiple user devices using transmission resources from a multi-dimensional grid of resources is described. The method includes logically partitioning the transmission resources into multiple segments, assigning, to a given user device of the multiple user devices, transmission resources of one or more of the multiple segments, and performing, using at least some of the assigned transmission resources for the given user device, a downlink transmission using an orthogonal time frequency space (OTFS) transformation on data or signals to be transmitted to the given user device.

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system to be provided in order to support a higher data transmission rate than a beyond 4th-generation (4G) communication system such as long term evolution (LTE). The present invention relates to a signal transmission method of a radio frequency (RF) processing device, the method comprising the steps of: generating a pulse signal including a control signal and a clock signal for obtaining synchronization with another RF processing device, which is connected through an interface; and transmitting, to the another RF processing device, at least one from among the pulse signal, a RF signal for communication with a base station, and a power signal for supplying power to the another RF processing device, wherein the clock signal and the control signal are assigned to different time units, and the pulse signal, the RF signal and the power signal are signals of different frequency bands.

Abstract: A system for multicarrier cellular communication in a cellular network including a multiplicity of nodes, the system comprising, at an individual moving relay from among the multiplicity of nodes, an rBS having downlink communication, according to a protocol, with UEs served thereby; and a co-located rRM (relay Resource Manager) having a controller; wherein the controller is operative to induce the rBS to generate a selective minimally interfered region in a domain and/or to coordinate between schedulers in the relay to ensure that each user has its own time and/or frequency such that channels do not overlap because time and/or frequency are shifted to prevent the overlap.

Abstract: A host device uses an intermediate frequency determined based on frequencies of a second-order nonlinear intermodulation distortion component and a harmonic component which are generated in an analog optical link connected to the host device, for example, an analog optical link of a distributed antenna system (DAS), and precompensates for the second-order nonlinear intermodulation distortion component and the harmonic component generated in the analog optical link.

Abstract: A communication apparatus includes a receiver, a combiner, and a transformer. The receiver receives signals mapped on plural frequency bands. A size of at least one of the frequency bands is a multiple of a product of two or more powers of prime numbers, which are integer numbers greater than 1 and are different from each other. An exponent for at least one of the prime numbers is an integer greater than 1. The combiner combines the received signals into a combined signal. The transformer transforms the combined signal in a frequency domain into a symbol sequence in a time domain with an inverse discrete Fourier transform (IDFT) having a size that is a product of powers of plural values. The values are integer numbers greater than 1 and are different from each other. An exponent for at least one of the values is an integer greater than 1.
