    摘要: A system and method using inverse-vector processing to iterate through a loop of three steps: set a guide direction, invert opposite vectors, and average vectors to update the guide direction, for smoothing seismic amplitude data. The inverse-vector method can overcome instabilities where the traditional structure-tensor approach fails. The inverse-vector smoothing is simple to implement and more computational efficient. The resultant dips and azimuths are spatially consistent and thus more interpretable and suitable for calculation of curvature and other dip based attributes.

    摘要: A system and method use 2D and 3D numerical gradient operators for reducing anisotropic inaccuracies in digital image processing. Enhanced isotropic operators are derived by first parameterizing corresponding numerical operators, followed by determining the parameters for the operators by matching analytical gradients with numerical gradients, which produces generic frequency-independent operators. The system and method also optimize the design of operators for use at any given frequency range needed for any special purpose application.

    摘要: A method and a device for feeding back and receiving downlink channel information are disclosed, whereby spectrum utilization ratio of downlink channel information feedback is enhanced. According to the present invention, a wireless terminal superposes an uplink user information sequence with spectrum-spread downlink channel information before transmission. A network side de-spreads a received signal before estimating the downlink channel information, and then detects the user information sequence after subtracting the estimated downlink channel information from the received signal. An orthogonal code can be employed to spread the spectrum of the downlink channel information. The wireless terminal and base station use a plurality of antennas for transmission and reception.

    摘要: Vehicle information (e.g., status information, calibratable parameters, or diagnostic data) is transmitted from a base station mounted in a vehicle to a portable RKE fob via a radio-frequency signal within a specified average field strength limit. A multi-byte vehicle message is formed and then coded into a multi-bit coded message. The multi-bit coded message is framed into a plurality of packets. The radio-frequency signal is wirelessly transmitted from the base station with a plurality of spaced packet windows having a predetermined duty cycle, each packet window including a respective one of the plurality of packets. The radio-frequency signal within each of the packet windows has a predetermined field strength greater than the average field strength limit and a substantially zero field strength between the packet windows. The predetermined duty cycle results in an actual average field strength for transmitting all of the packets not exceeding the average field strength limit.
