The location-estimating, null-steering (LENS) algorithm for adaptive microphone-array processing
… (LENS) algorithm for adaptive array beamforming in the case of a. known target location. Such beamformers are useful in spatial-filtering applications that enhance a desired target source while attenuating non-target, jammer sources in a given environment. Although LENS is designed …

Sum-rate maximization in multi-RIS multi-carrier systems through active power allocation and passive beamforming
… power at the base station (BS) and the passive beamforming of RIS reflecting elements to maximize the achievable rate at the user’s location. Three RIS reflection model assumptions are considered and analyzed. In Scenario A, we establish upper and lower bounds for the sum-rate maximization …

Robust multi-group multicast beamforming design and antenna selection for massive MIMO systems
… algorithm to design robust multi-group multicast beamforming scheme for massive multiple-input multiple-output (MIMO) systems for two scenarios; 1) all antennas are available at the base station (BS), 2) only subset of antennas are available due limitation on the number of RF chains (joint antenna …

Design, Characterization and Application of a Multiple Input Stethoscope Apparatus
<p>For this project, the design, implementation, characterization, calibration and possible applications of a multiple transducer stethoscope apparatus were investigated. The multi-transducer sensor array design consists of five standard stethoscope diaphragms mounted to a rigid frame for a-priori …
