Soft-decision Star-QAM aided BICM-ID

open access: yes, 2011
Differentially detected non-coherent Star Quadrature Amplitude Modulation (Star-QAM) is deal for low-complexity wireless communications, since it dispenses with high-complexity channel estimation. We conceive soft-decision based demodulation for 16-level

Phase dependent modulation of tremor amplitude in essential tremor through thalamic stimulation [PDF]

open access: yes, 2013
High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition.

Signal regeneration techniques for advanced modulation formats

open access: yes
We review recent results on all-optical regeneration of phase encoded signals based on phase sensitive amplification achieved by avoiding phase-to-amplitude conversion in order to facilitate the regeneration of amplitude/phase encoded (QAM ...

Network coded modulation for two-way relaying [PDF]

open access: yes, 2011
Network coding compresses multiple traffic flows with the aid low-complexity algebraic operations, hence holds the potential of significantly improving both the power and bandwidth efficiency of wireless networks.

Semi-blind adaptive beamforming for high-throughput quadrature amplitude modulation systems

open access: yes, 2010
A semi-blind adaptive beamforming scheme is proposed for wireless systems that employ high-throughput quadrature amplitude modulation signalling. A minimum number of training symbols, equal to the number of receiver antenna arrays elements, are first ...

Modulator-free quadrature amplitude modulation signal synthesis

open access: yes, 2014
The ability to generate high-speed on-off-keyed telecommunication signals by directly modulating a semiconductor laser’s drive current was one of the most exciting prospective applications of the nascent field of laser technology throughout the 1960s ...

Adaptive minimum symbol error rate beamforming assisted receiver for quadrature amplitude modulation systems

open access: yes, 2006
An adaptive beamforming assisted receiver is proposed for multiple antenna aided multiuser systems that employ bandwidth efficient quadrature amplitude modulation (QAM).

Reading television after 25 years: A new foreword by John Hartley

open access: yes, 2003
Reading Television was the first book to push the boundaries of television studies beyond the insights offered by cultural studies and textual analysis, creating a vibrant new field of study.

Maximum Euclidean distance network coded modulation for asymmetric decode-and-forward two-way relaying

open access: yes, 2013
Network coding (NC) compresses two traffic flows with the aid of low-complexity algebraic operations, hence holds the potential of significantly improving both the efficiency of wireless two-way relaying, where each receiver is collocated with a ...
