Abstract: A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.

Abstract: Strain-gated logic devices are important for the development of advanced flexible electronics. Using a dual-monolayer-promoted film-transfer technique, a flexible multilayer structure capable of undergoing large compressive deformation was prepared. Formation of a crease in the gap between electrodes at a geometrically tunable strain leads to formation of an electrical connection in a reversible and reproducible fashion. A strain-gated electrical switch includes at least two conductive electrodes disposed on a surface of an elastomer substrate, the at least two conductive electrodes forming a gap between the at least two electrodes in an off-state of the strain-gated electrical switch, the gap diminishing under compressive strain to form a crease, the compressive strain pressing the at least two electrodes into contact with each other in an on-state of the strain-gated electrical switch.

Abstract: Method and apparatus of obtaining better detection performance by improving matrix condition for an M×N over-determined MIMO system are disclosed. The condition of a matrix to be inverted for solving various detection problems is improved by reordering equations of the original MIMO system, resulting in a reordered channel matrix and reordered received signal vector so that the top N×N sub-matrix has the largest determinant among all N×N sub-matrices of the reordered channel matrix. The disclosed method may be used to obtain a more accurate estimate of the transmit data bits.

Abstract: A method includes estimating spatial signatures of the signal and interference data streams, forming a composite channel matrix comprising all or a subset of estimated spatial signatures, performing QR decomposition (QRD) of channel matrix with different spatial orderings, selecting the stream with the largest post-detection signal-to-interference-plus-noise ratio (SINR) based on the elements of the R matrices from different QRD processes, pre-processing received signal using the Q matrix corresponding to the spatial ordering with the largest SINR, demodulating the strongest stream using single-stream sliced maximum likelihood (SSS-ML) method, cancelling the strongest stream and demodulating the remaining weaker streams using low-complexity MMSE method.

Abstract: Techniques for minimum-mean-square-error (MMSE) channel estimator using channel-dependent composite subcarriers and combined pilots reduce computational complexity and memory usage while still achieving near optimum performance. A set of interpolation filters, that are pre-calculated for different radio propagation environments, e.g., channel state information, are stored in look up tables at the receiver and used to interpolate channel estimates for combined pilots to obtain channel estimates for individual subcarriers.

Abstract: A receiver for demodulating wireless signal using multiple receive antennas includes multiple signal detection modules, with each module implementing a non-interference rejection combining signal detection technique. The receiver makes a decision about whether or not to use an interference rejection combining technique, and which signal detection module to use based on the operating conditions of the received signals. When the decision is made to use an interference rejection combining technique, a single whitening filter is used to whiten the received signal prior to sending the whitened signal for processing by the signal detection module. The whitening filter may be calculated as a Cholesky decomposition of an impairment covariance matrix generated from the signals received at the multiple antennas.
