Abstract: Embodiments of a system and method for generating a shaped cyclic time-domain waveform are generally described herein. In some embodiments, a first transform may be performed on an input symbol vector to generate a transformed input vector in a transform domain. The transformed input symbol vector may be expanded to generate an expanded symbol vector. At least some elements of the expanded symbol vector may be weighted with a weighting vector selected for pulse shaping to generate a weighted symbol vector. A second transform may be performed on the weighted symbol vector to generate an output symbol vector for subsequent processing and transmission. The second transform may be an inverse of the first transform and may comprise a greater number of points than the first transform.

Abstract: A system and method for secure substring search, using fully homomorphic encryption, or somewhat homomorphic encryption. In one embodiment, a first string is homomorphically compared to trial substrings of a second string, each comparison producing a ciphertext containing an encrypted indication of whether the first string matches the trial substrings. These ciphertexts are then combined in a homomorphic logical OR operation to produce a ciphertext which contains an encrypted indication of whether the first string matches any of the trial substrings, i.e., whether the first string is contained in the second string.

Abstract: An approach to computation of kernel descriptors is accelerated using precomputed tables. In one aspect, a fast algorithm for kernel descriptor computation that takes O (1) operations per pixel in each patch, based on pre-computed kernel values. This speeds up the kernel descriptor features under consideration, to levels that are comparable with D-SIFT and color SIFT, and two orders of magnitude faster than STIP and HoG3D. In some examples, kernel descriptors are applied to extract gradient, flow and texture based features for video analysis. In tests of the approach on a large database of internet videos used in the TRECVID MED 2011 evaluations, the flow based kernel descriptors are up to two orders of magnitude faster than STIP and HoG3D, and also produce significant performance improvements. Further, using features from multiple color planes produces small but consistent gains.

Abstract: Embodiments of a near-field communication (NFC) system and method for private near-field communication are generally described herein. In some embodiments, a resonance-coupled channel is masked with a random channel-masking signal. The channel-masking signal may be scaled based on near-field channel conditions. Signals received through the channel may be unmasked with the scaled channel-masking signal to determine data that may have been conveyed by an NFC transmitting device by affecting the impedance of the resonance-coupled channel. In some embodiments, a reference signal may be scrambled with a mask to generate the channel-masking signal. The mask may include at least one of a random symbol mask, an amplitude mask and a phase mask. For additional privacy, the mask may include a random symbol mask and at least one of an amplitude mask and a phase mask.
