Applications of iterative decoding to magnetic recording channels.
(2002)
Finally, Q-ary LDPC (Q-LDPC) codes are considered for MRCs. Belief propagation decoding for binary LDPC codes is extended to Q-LDPC codes and a reduced-complexity decoding algorithm for Q-LDPC codes is developed. Q-LDPC ...
An optimally well-localized multi-channel parallel perfect reconstruction filter bank.
(2003)
Joint uncertainty for the overall L-channel, one-dimensional, parallel filter bank is quantified by a metric which is a weighted sum of the time and frequency localizations of the individual filters. Evidence is presented ...
Coverage issues in wireless sensor networks.
(2006)
A fundamental issue in the deployment of a large scale Wireless Sensor Network (WSN) is the ability of the network to cover the region of interest. While it is important to know if the region is covered by the deployed ...
CYLINDRICAL POLARIMETRIC PHASED ARRAY RADAR DEMONSTRATOR: PERFORMANCE ASSESSMENT AND WEATHER MEASUREMENTS
(2020-07-30)
A desirable candidate for future weather observation is a polarimetric phased array radar (PPAR), which is capable of both using polarimetry for multi-parameter measurements and the fast-scan proficiency of the PAR. However, ...
Improved nonlinear filtering for target tracking.
(2007)
The objective of this research is to develop robust and accurate tracking algorithms for various tracking applications. These tracking problems can be formulated as nonlinear filtering problems. The tracking algorithms ...
Impurity scattering in a two-dimensional electron gas subject to a perpendicular magnetic field.
(1998)
We have calculated the Landau level (projected) Green's functions and the density of states of a two-dimensional electron gas in a perpendicular magnetic field as effected by impurity scattering using several different ...
Mid-infrared emitter technology.
(2006)
As part of an effort to improve heat dissipation from mid-infrared laser materials during operation, work was performed on mounting laser bars in an epi-side-down configuration. Results obtained from packaging interband ...
A new method for realizing parallel processing machines using multiple-valued logic.
(1980)
Parallel processing machines that can perform two or more operations simultaneously have been constructed to provide concurrent operation of identical or highly similar system components. Currently, parallel operation is ...
