A system and method are provided to increase data rates available in mmWave wireless communication systems by adapting a multiple-input multiple-output (MIMO) in a next generation mmWave wireless communication system. The system and method advantageously employ the characteristics of mmWave antenna arrays, including multiple antenna elements in each antenna array, to implement the MIMO scheme by establishing multiple beamformed communication links between a mmWave transmitter and receiver. An outgoing signal is divided into multiple signal elements to correspond to the multiple beamformed links and each of the multiple signal elements is transmitted by the transmitter across a different one of the multiple beamformed links to be reassembled at the receiver. An antenna element allocation scheme is incorporated to assign specific numbers and configurations of antenna elements at each of the transmitted and receiver to each of the multiple beamformed communication links.

A method and system for identification, tracking and locating in wireless communications and wireless networks. The method and system use reference and / or pilot signals that are present in wireless communications and wireless networks. The method and system might also use RTT, TOA and time-stamping measurements / techniques to determine one or more reference signals traveling time between the Base Station (eNB) or its functional equivalent and mobile device (UE) and or network device. Other wireless networks that do not use reference and / or pilot signals may employ one or more of the following types of alternate embodiments of present invention: 1) where a portion of frame is dedicated to the ranging signal / ranging signal elements; 2) where the ranging signal elements are embedded into (spread across) transmit / receive signals frame(s); and 3) where the ranging signal elements are embedded with the data. The method and system includes multi-path mitigations processor and multi-path mitigations techniques and algorithms which improve the track-locate accuracy. The method and system allow achieving increased accuracy by using multi-path mitigations processor and multi-path mitigations techniques and algorithms. The techniques of Digital Signal Processing and Software-Defined Radio are used.

A system and method for determining from an arbitrary signal a characteristic signature or other characterizing feature and for distinguishing signals associated with one specific condition from those associated with one or more other conditions. The system uses dictionaries of plural sets of basis signal elements, for example, combinations of orthogonal bases with different characteristics. It optimizes the fit of part of an arbitrary signal to one or more elements of one class of basis signals from a dictionary and iteratively fits the remainder of the arbitrary signal to elements of an optimal class of basis signals, either the original or a different class depending on the goodness of match between the residual part of the signal and the subsequent basis class.

The invention relates to transfer of packet data from a first subsystem via a network node in a second subsystem to a terminal in the second subsystem. The method includes negotiating identifiers identifying a data flow of the first subsystem via a separate signalling element during the set-up of an application-plane logical connection of the terminal. The identifiers are transmitted from the signalling element to the network node. In the method, a filter is generated at least on the basis of the identifiers for directing the mapping of at least one data flow of the first subsystem to at least one data flow of the second subsystem. The filter is bound to at least one data flow of the second subsystem, and at least one data flow of the first subsystem is mapped to at least one data flow of the second subsystem on the basis of the filter.

A vehicle safety lighting and signaling system includes a transmitting unit and multiple remote receiving units, each having a lighting and audible element, and that receive signals from the transmitting unit and selectively activates its signaling elements according to a predetermined signal response directed by the transmitting unit. The receiving unit includes a central processor that selectively decodes transmitted signals received from the transmitting unit and provides signals to a driver circuit that activate a visual signal, and audible signal, or both. A receiving unit may have an integral base affixed to an adjustable band, clothing or motorcycle, and that receiving unit is detachable from the base for charging and / or programming. The remote receiving units may include a band that is expandable for positioning about a cycle riders' arm or leg, and includes one or more lighting elements responsive to receiving a predetermined signal.

The invention relates to trimming of analogue filters (201) in integrated circuits by means of an automatic adjusting circuit. A local oscillator (202) in the automatic adjusting circuit provides a periodic reference signal (R) to an adjustable phase shifter (203), which on basis thereof, produces a periodic phase shifted signal (R*). A phase detector (204) receives both the periodic reference signal (R) and the phase shifted period signal (R*) and produces a test signal (T) in response to a phase difference between the periodic reference signal (R) and the periodic phase shifted signal (R8). A lowpass filter (205) receives the test signal (T) and generates a level signal (TDC) relative a reference level, e.g. representing a zero voltage. A digital signal processor (207) produces a primary control signal (CS), having a serial format, on basis of the observation signal (M). A serial-to-parallel converter (208) converts the primary control signal (CS) into a control signal (CP) having a parallel signal format. The control signal (CP) influences a magnitude of at least one component value in the adjustable phase shift between the periodic reference signal (R) and the periodic phase shifted signal (R*) attains a calibrated value being as close as possible to a desired value. A latch (210) forwards at least one signal element of the control signal (CP) for setting of at least one component value in the analogue filter (201) in accordance with a setting of at least one component value in the adjustable phase shifter (203) which produces the calibrated value.

The present invention discloses an explicit signaling element for controlling decoded picture output and applications when picture output is not desired. A signal element, such as a syntax element in a coded video bitstream, is used to indicate (1) whether a certain decoded picture is output; (2) whether a certain set of pictures are output, wherein the set of pictures may be explicitly signaled or implicitly derived; or (3) whether a certain portion of a picture is output. The signal element may be a part of the coded picture or access unit that it is associated with, or it may reside in a separate syntax structure from the coded picture or access unit, such as a sequence parameter set. The signal element can be used both by an encoder and a decoder in a video coding system, as well as a processing unit that produces a subset of a bitstream as output.
