  • Publication number: 20220012995
    Abstract: Disclosed herein is an active cyclist and/or pedestrian safety system for identifying, warning, and reacting to dangerous situations that may be experienced by cyclists and/or pedestrians. The safety system may receive first information indicative of a head position of a cyclist and determine, based on the first information, a field of view of the cyclist. The safety system may receive second information indicative of an environment of the cyclist and determine, based on the field of view and the environment, an expected trajectory of the cyclist in a next road segment. The safety system may also determine, based on the field of view and the environment, a risk probability for the expected trajectory of the cyclist in the next road segment. The safety system may also generate an instruction to transmit a warning to the cyclist if the risk probability exceeds a threshold value.

  • Publication number: 20170188300
    Abstract: The disclosure generally relates FTM measurements using a network of Access Points (APs) and FTM responders to provide location information to an inquiring mobile device. In one embodiment, the disclosure provides significant power conservation by allowing an AP to communicate with the user equipment (e.g., mobile device) seeking its location. The AP can relay information about availability of an FTM Responder to the user equipment thereby directing the user equipment to transmit its FTM Request directly to the FTM Responder during the Responder's availability window. The disclosed embodiment enable significant power conservation for the FTM Responder thereby extending the battery life of the Responder.

  • Publication number: 20100234071
    Abstract: A novel and useful vehicle integrated communications system that provides a solution to the poor performance experienced at the cell edge in a cellular communications system due to weak signal strength and high interference levels. A core cellular communications platform embedded (integrated) into the vehicle platform utilizes multiple antennas integrated into the body of the vehicle which are coupled to a multi-antenna transceiver; receives electrical power from the vehicle power source eliminating the limitations of hand held device batteries; processes multiple MIMO RF signals taking advantage of antenna diversity, beamforming and spatial multiplexing; executes advanced interference mitigation algorithms; implements adaptive modulation and coding algorithms; and utilizes dynamic channel modeling and estimation to significantly improve performance.

  • Publication number: 20080233966
    Abstract: A novel and useful method and system for resource allocation in OFDM communication systems. The mechanism reduces inter-cell interference by randomizing the inter-cell interference experienced in each cell. The mechanism effectively spreads the resource allocation in each cell in a random manner resulting in statistical-like inter-cell interference behavior. In many cases, use of the mechanism is sufficient to obviate the need for frequency planning between cells. A formula or hardware permutation machine is used to generate a random list of indices. The indices are then used to assign user data to the system resources. One or more parameters defining the random index generator at the transmitter are forwarded to the receiver to enable the local generation of an exact copy of the list of indices generated at the transmitter, thus enabling the DL and UL at the receiver while minimizing the required control channel signaling.

  • Publication number: 20080192622
    Abstract: A novel and useful method and system for control channel signaling for use in multiple access wireless communication systems. The control message portion of the frame is divided into two portions: a first portion for transmitting a list of u-ID information and a second portion for transmitting all other remaining control information. All user identification information (u-ID information) is placed at the beginning of the control portion of a frame, typically in one or two symbols sent in the earliest part of the frame. The remaining control information (i.e. resource allocation and decoding information) is sent in the second portion of the control message. Users that do not have a resource assignment in a frame can skip the remainder of the frame, including the rest of the control message and data, and shutdown their receivers thus reducing power consumption. Only those UEs served in the current frame need to continue reception and decoding of the remainder of the control message and subsequent data.

  • Patent number: 7061967
    Abstract: A method and apparatus for estimating channel tap delays of multipath components in a CDMA received signal. The search for the tap delays are split into two phases namely, a phase 1 and a phase 2 search. The phase 1 search is a coarse resolution quick search adapted to generate a rough estimate of the location of the tap delays. During this phase, the candidate codes are summed and the input signal correlated with the code sum creating an ambiguity in the code associated with the multipath. A finer resolution slower phase 2 search resolves the code ambiguity present in the initial rough estimates of the phase 1 search. Additional phase 2 correlations may be performed to implement a code-tracking loop.

  • Patent number: 6862326
    Abstract: A novel and useful whitening matched filter (WMF) for use in a communications receiver. The WMF is constructed by cascading a matched filter and a noise-whitening filter. The response of the matched filter is derived from the time reversed complex conjugate of the channel impulse response. The whitening filter is derived by extracting the minimum phase portion of the mixed phase channel impulse response using homomorphic deconvolution. The whitening filter is implemented using either an FIR or IIR filter adapted to process the data received before and after the training sequence using a minimum phase system in a direction in time opposite to that of the direction of corresponding data sample processing performed by the equalizer.

  • Patent number: 6065078
    Abstract: A multiprocessor system includes a plurality of processors. A debugger interface includes interface circuitry to interface the plurality of processors to a debugger. The debugger interface includes means for receiving a debugger command from the debugger. Debugger command directing means determines from the debugger command for which of at least one of the plurality of processors the debugger command is intended, directs the debugger command, via the interface circuitry to the at least one intended processor. A processor command is received from one of the plurality of processors, and processor command directing means directs the processor command, received from the one processor, via the interface circuitry to the debugger. The system is especially suited for debugging software that is executing on the plurality of processors of the multiprocessor system.

  • Patent number: 5631957
    Abstract: Near-end echo-reduction is achieved by passing a transmit signal through a first filter bank and feeding a remote signal plus an echo of the transmit signal through a second filter bank, then subtracting a gain-coefficient-compensated (scaled) version of the filtered transmit signal from the filtered-composite-remote signal to obtain an echo-reduced receive signal. The echo-reduced receive signal is suitably employed by tone decoders, voice response mechanisms, and the like, in a telephone system, and avoids false alarms due to near-end echo. In one embodiment, the gain coefficients are fixed for each frequency of interest. In another embodiment, the gain coefficients are dynamically arrived at based on the filtered transmit signal and the echo-reduced receive signal. The two filter banks can be combined in one, multiplexed filter bank.
