LDPC-OFDM: Channel Estimation and Power considerations
(2013-04-29)Small cells are low-powered radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to 200 meters, compared to a mobile macrocell which might have a range of a few kilometres. ... -
Likelihood-Based Modulation Classification for Multiple-Antenna Receivers
(2012-09-21)Prior to signal demodulation, blind recognition of the modulation scheme of the received signal is an important task for intelligent radios in various commercial and military applications such as spectrum management, ... -
Linear Hyperspectral Unmixing Using L0-norm Approximations and Nonnegative Matrix Factorization
(2016-10-05)Spectral unmixing (SU) is a technique to characterize mixed pixels of the hyperspectral images measured by remote sensors. Most of the existing spectral unmixing algorithms are developed using the linear mixing models. ... -
Link Adaptation for Energy Constrained Networks
(2008-12-02)Relay terminals are often used in tandem in sensor networks to lessen nodal communication burden. In this light we investigate the problem of power allocation amongst nodes in a relay network in order to maximize the overall ... -
Localization of Human Pelvis Anatomical Coordinate System Using Ultrasound Registration to Statistical Shape Model
(2010-08-24)Total Hip Replacement (THR) has become a common surgical procedure in recent years, due to the increase in the aging population with hip osteoarthritis. Identifying the proper orientation of the pelvis is a critical step ... -
A low feedback robust opportunistic scheduler and beamformer for MISO wireless systems
(2007-07-06)Opportunistic Beamforming is a promising scheme with potential usage in a variety of applications ranging from cellular audio/video communications to wireless mesh-networks. However, some aspects in this scheme are open ... -
