Nonlinear effects in lte downlink signals and application of a compensation technique at the receiver side
(Wiley, 2012-01)
This article proposes a nonlinear compensation technique for long-term evolution downlink signals based on the memoryless solid-state power amplifier model, which provides a simple and effective linearization technique at ...

Digital predistortion technique with in-band interference optimisation applied to DVB-T2
(The Institution of Engineering and Technology, 2012-05)
The efficient transmission and nonlinear modelling of orthogonal frequency division multiplexing (OFDM) signals are difficult to address owing to the special characteristics of this modulation scheme. Proposed is a digital ...

A Real-Time, Event Driven Neuromorphic System for Goal-Directed Attentional Selection
(Springer Verlag, 2012)
Computation with spiking neurons takes advantage of the abstraction of action potentials into streams of stereotypical events, which encode information through their timing. This approach both reduces power consumption ...

Efficient feedforward categorization of objects and human postures with address-event image sensors
(Institute of Electrical and Electronics Engineers, 2012)
This paper proposes an algorithm for feedforward categorization of objects and, in particular, human postures in real-time video sequences from address-event temporal-difference image sensors. The system employs an innovative ...
