Digital signal processing on the unit sphere via a Ramanujan set of rotations and planar wavelets.
(2000)
We give a sufficient condition for a zonal function to be a strictly positive definite. A major result of this thesis is that we have proven Shreiner's result as a consequence of a more general representation-theoretic ...
Error-correction coding for high-density magnetic recording channels.
(2004)
Finally, a promising algorithm which combines RS decoding algorithm with LDPC decoding algorithm together is investigated, and a reduced-complexity modification has been proposed, which not only improves the decoding ...
Towards Efficient and Enhanced Wireless Coexistence in the Unlicensed Spectrum
(2021-07)
The 3rd Generation Partnership Project (3GPP) is developing the fifth generation (5G) of wireless broadband technology and has identified the unlicensed spectrum as a principal item on the plan of action. Listen-Before-Talk ...
Passive Radar Clutter Modeling and Emitter Selection for Ground Moving Target Indication
(2017-08-01)
Moving target detection with a passive radar system relies on many competing and coupled variables. When simulating a passive bistatic radar (PBR) system for ground moving target indication (GMTI) a three-dimensional model ...
Spiral top loaded antenna :
(1972)
Development of a thermoelectrically cooled IV-VI semiconductor diode laser using epitaxial lift-off techniques.
(1997)
A potential solution to the operating temperature problem is to employ epitaxial lift-off techniques in order to transfer the semiconductor device from its thermally resistive substrate to copper, a superior thermal ...
Designing data-aided demand-driven user-centric architecture for 6G and beyond networks
(2023-08-04)
Despite advancements in capacity-enhancing technologies like massive MIMO (multiple input, multiple output) and intelligent reflective surfaces, network densification remains crucial for significant capacity gains in future ...
Digital-At-Every-Element Radar Resource Allocation for Multi-Target Tracking
(2019-05)
A sensor's performance is constrained by the amount of resources at its disposal and the utilization of those resources. A radar system, for example, has a limited amount of transmit power-aperture per unit time to track ...
Interband Cascade Structures for Infrared Photodetectors and Thermophotovoltaic Devices
(2016-12-16)
Interband cascade (IC) devices are a family of quantum engineered heterostructures that include: IC lasers (ICLs), IC infrared photodetectors (ICIPs) and IC thermophotovoltaic (ICTPV) devices. In these structures, the ...
Exploiting Heterogeneous Multicore Processors Through Fine-Grained Scheduling and Low-Overhead Thread Migration
(2012)
Heterogeneous (also known as asymmetric) multicore processors (HMPs) offer significant advantages over homogeneous multicores in terms of both power and performance. Power-efficient cores can be paired with higher-performance ...
