  • Patent number: 8665647
    Abstract: A non-volatile memory device performs a read operation for compensating for coupling due to an adjacent memory cell. With the read operation of the non-volatile memory device, the coupling effect included in a read result of the selected memory cell is compensated on the basis of a program state of an adjacent memory cell adjacent to the selected memory cell. Toward this end, a read operation for the adjacent memory cell is selectively performed before the selected memory cell is read. Upon sensing of data from the selected memory cell, one or more read operations for the selected memory cell are performed according to the program state of the adjacent memory cell with a read voltage being changed in level depending on the program state of the adjacent memory cell.

  • Patent number: 8665690
    Abstract: A system for providing energy assisted magnetic recording (EAMR) heads using a substrate is described. The substrate has front and back sides and apertures therein. The apertures are through-holes between the front and back sides of the substrate. The system includes providing a transmission medium in the apertures and fabricating EAMR transducers on the front side of the substrate. The EAMR transducers correspond to the apertures and the EAMR heads. The system also includes electrically insulating the back side of the substrate. The back side of the substrate is also prepared for mounting of the lasers. The lasers then are coupled the back side of the substrate. The lasers correspond to the EAMR heads and are configured to provide light through the apertures to the EAMR transducers. The system also includes separating the substrate into the EAMR heads.

  • Patent number: 8665693
    Abstract: A system and method are provided for Soft Interference Cancellation (SIC) in receiving Single Carrier Frequency Division Multiple Access (SC-FDMA) Multiple-Input Multiple Output (MIMO) signals. A receiver with Mr antennas accepts multicarrier signals transmitted simultaneously, with N overlapping carrier frequencies. The receiver removes a cyclic prefix (CP), and fast Fourier transforms (FFT) the multicarrier signal from each antenna, supplying Mr number of N-tone signals y. Using either parallel SIC (P-SIC) or successive SIC (S-SIC), interference is canceled in each of the Mr signals, and soft symbols are supplied for each of U layers. Interference is canceled using the P-SIC process by parallel processing the U layers in an i-th iteration, in response to feedback from an (i?1)th iteration. Alternatively, interference is canceled using the S-SIC process by sequentially processing the U layers in an i-th iteration, in the order of u0,u1, . . . , uU?1, using feedback generated from previously processed layers.

  • Patent number: 8665694
    Abstract: Systems and methods are provided for transmitting information between an intended source and a receiver to minimize co-channel interference from at least one interfering source. Pilot subcarriers and data subcarriers may be broadcast from an intended source arid at least one interfering source. The pilot subcarriers may be shared across base stations or distributed among base stations in frequency, in time, or both. In addition, the frequency reuse factor of the pilot subcarriers may be different than the frequency reuse factor of the data subcarriers. A receiver receives a composite signal that corresponds with an intended signal from an intended source and an interfering signal from at least one interfering source. The portion of the received signal that corresponds to the intended signal may be recovered by the receiver based on the broadcast of the pilot subcarriers.

  • Patent number: 8665695
    Abstract: A communications apparatus is provided. A receiving module receives a signal with a predetermined signal bandwidth. A low pass filter filters the signal to obtain a filtered signal. A filter bandwidth of the low pass filter is wide enough to pass the regular sub-carrier frequency components and at least half of the guard sub-carrier frequency components of the signal. An analog to digital converter samples the filtered signal with a sampling rate exceeding a standard sampling rate defined in accordance with the predetermined signal bandwidth of the signal to obtain a plurality of digital samples. A Fast Fourier Transform module performs a fast Fourier transform on a predetermined number of points of the digital samples to obtain a plurality of transformed samples. The predetermined number exceeds a standard number defined in accordance with the predetermined carrier bandwidth. A sub-carrier collector collects the data from the transformed samples.

  • Patent number: 8665696
    Abstract: An OFDM system uses a normal mode which has a symbol length T, a guard time TG and a set of N sub-carriers, which are orthogonal over the time T, and one or more fallback modes which have symbol lengths KT and guard times KTG where K is an integer greater than unity. The same set of N sub-carriers is used for the fallback modes as for the normal mode. Since the same set of sub-carriers is used, the overall bandwidth is substantially constant, so alias filtering does not need to be adaptive. The Fourier transform operations are the same as for the normal mode. Thus fallback modes are provided with little hardware cost. In the fallback modes the increased guard time provides better delay spread tolerance and the increased symbol length provides improved signal to noise performance, and thus increased range, at the cost of reduced data rate.
