摘要： Method and apparatus for detecting whether load coils are attached to a telephone line. A stimulus waveform having multiple frequency components is applied to the line. The current and voltage at the near end of the line are coherently sampled and transformed to the frequency domain. The frequency spectra are used to compute auto and cross power spectra of the current and voltage. These power spectra are then used to compute the impedance on the line as well as a coherence function that indicates the extent to which the computed impedance was influenced by noise. If the coherence values indicate that the computed impedance is sufficiently reliable, load coils are detected by finding peaks in the magnitude of the impedance function or sign changes in the phase of the impedance function. Calibration, offset adjustments and ensemble smoothing are used to increase the accuracy of the results. The computation is fast because computing the spectra avoids the need for individual measurements at multiple frequencies. The computation is accurate because it is not sensitive to noise.

摘要： Methods, system and apparatuses for carrier frequency offset estimation are disclosed. The method includes: receiving a preamble sequence rn with a correlator and correlating the preamble sequence with a locally stored Barker code bn to obtain a correlation result cn; extracting peak values from every L points in cn to form a peak value sequence xn, L being a length of a Barker code that corresponds to the sampling rate; performing frequency offset estimation to xn by using at least two frequency offset estimation apparatuses, the at least two frequency offset estimation apparatuses adopting different delay parameters D; and inputting the results output from the at least two frequency offset estimation apparatuses into a frequency offset combination module to calculate a final carrier frequency offset estimate, whereby accurate frequency estimation can be achieved and an appropriate acquisition range of frequency offset can be ensured.

摘要： Methods and apparatuses for channel estimation are disclosed. The method includes: converting −1's in a local Barker code to 0's; receiving a first preamble symbol output from a first Barker correlator and a second preamble symbol output from a second Barker correlator with a symbol determination module, the first preamble symbol being adjacent to the second preamble symbol; multiplying a result output from the symbol determination module with a correlation result output from the cyclic Barker correlator by using a multiplication module so as to obtain a channel estimation response; and receiving channel estimation responses with a time-domain channel data storage unit, and averaging them to obtain a noise-reduced channel estimation response. The channel estimation method and apparatus of the present invention can be achieved based on few hardware resources and low computation complexity.

摘要： The disclosed subject matter relates to providing a view synthesis distortion model (VSDM) for multiview video coding (MVC). The disclosed VSDM can facilitate determining quantization values and rate values based on model parameters for encoding depth information. Further, the VSDM can facilitate compression of depth information based on the determined quantization values and rate values. Compression of depth information can provide for reduces bandwidth consumption for dissemination of encoded multiview content for applications such as 3D video, freepoint TV, etc. Further, a feedback element can be employed to update the VSDM based on a comparison of a reconstituted version of the content, from coded depth information, against reference version of the content, from reference depth information.
