摘要： A method for piloting from bypass in a network with open wireless channels is disclosed. The method includes: 1) selecting a terminal station as a reference in open wireless channels, and sending a pilot signal, in which all or some frequency bands of open wireless channels occupied by the pilot signal are pilot frequency bands, and the proportion of power of the pilot signal to the total power of the pilot frequency bands is 0.1‰-5%; 2) spreading the pilot signal with a spread spectrum code when it is transmitted, and then superimposing on a communication signal in the pilot frequency bands in a low power spectrum signal mode similar with noise; and 3) providing pilot, carrier wave and clock synchronization, standard timing and indication information for network construction and mutual communication of multiple types of terminal stations in channels by the pilot signal.

摘要： Systems, apparatuses, and methods for implementing efficient power optimization in a computing system are disclosed. A system management unit configured to track computing activity of a computing device while processing each frame of a plurality of frames. The computing activity is tracked at least for a given period of time comprising a plurality of time slices. The system management unit further correlates a time slice associated with a given frame with a time slice associated with at least one previously processed frame from the plurality of frames, based at least in part on the tracked computing activity. The system management unit predicts a clock frequency to render the given frame, based at least in part on the correlation and renders the given frame using the predicted clock frequency.

摘要： Provided are a method and an apparatus for performing, by a first device, wireless communication.

摘要： A timing detection device includes a main reference code generation module, an auxiliary reference code generation module, a first correlation processing module, a second correlation processing module, and a subtraction module. The main reference code generation module generates a main reference code consisting of the same code for synchronization included in a received signal. Using a portion of the same code as the code for synchronization, the auxiliary reference code generation module generates an auxiliary reference code consisting of a code configuration different from the main reference code and without generating a main lobe during correlation processing. The first correlation processing module correlates the received signal with the main reference code and outputs a first correlation result. The second correlation processing module correlates the received signal with the auxiliary reference code and outputs a second correlation result. The subtraction module subtracts the first correlation result from the second correlation result.

摘要： A system for includes master and sniffer devices. The master device includes: first antennas with different polarized axes; a transmitter transmitting a challenge signal via the first antennas from the vehicle to a slave device, where the slave device is a portable access device; and a receiver receiving a response signal in response to the challenge signal from the slave device. The sniffer device includes: second antennas with different polarized axes; and a receiver receiving, via the second antennas, the challenge signal from the transmitter and the response signal from the slave device. The sniffer device measures when the challenge signal and the response signal arrive at the sniffer device to provide arrival times. The master or sniffer device estimates at least one of a distance from the vehicle to the slave device or a location of the slave device relative to the vehicle based on the arrival times.

摘要： The presence or absence of a preamble is detected with accuracy in a reception apparatus that receives a signal including a preamble.
A reception section receives a subframe including a subframe preamble and a message and a frame including a frame preamble. A processing section performs a process of detecting the presence or absence of the subframe preamble according to whether or not a given relation holds between a reception timing of the subframe preamble and a reception timing of the frame preamble. A message decoding section extracts the message from the subframe and decodes the message in a case where the presence of the subframe preamble is detected.

摘要： Aspects of the embodiments are directed to systems, methods, and computer program products that facilitate a downstream port to operate in Separate Reference Clocks with Independent Spread Spectrum Clocking (SSC) (SRIS) mode. The system can determine that the downstream port supports one or more SRIS selection mechanisms; determine a system clock configuration from the downstream port to a corresponding upstream port connected to the downstream port by the PCIe-compliant link; set an SRIS mode in the downstream port; and transmit data across the link from the downstream port using the determined system clock configuration.
