Sparse adaptive constant blind equalization algorithm for sparse multipath channel
Tongxin xuebao, 2017 In order to improve the convergence rate of the blind equalizer for sparse multipath channel,a novel blind equalization approach called l0-norm constraint proportionate normalized least mean square constant algorithm was proposed for M-order phase-shift ...

Channel Equalization Using Multilayer Perceptron Networks [PDF]
Mehran University Research Journal of Engineering and Technology, 2012 In most digital communication systems, bandwidth limited channel along with multipath propagation causes ISI (Inter Symbol Interference) to occur. This phenomenon causes distortion of the given transmitted symbol due to other transmitted symbols.

The Role of Skills and Tasks in Gender Gaps in Latin America
Review of Development Economics, EarlyView.ABSTRACT In this paper, we explore gender gaps in the labor market in Latin America, incorporating two relevant factors often overlooked: skills and the type of tasks performed at work. The study is based on data from the 2018 Program for the International Assessment of Adult Competencies (PIAAC) for four Latin American countries.

Blind System Identification Using Symbolic Dynamics
IEEE Access, 2018 In this paper, a chaos-based approach is proposed for system identification with binary random signal. A chaos-based approach is developed to model random binary sequence and is applied to blind system identification.

Sociological Forum, EarlyView.ABSTRACT Non‐governmental organizations (NGOs) rely on donor support to pursue their missions. As such, NGOs may forgo initiatives that do not appeal to constituents, such as racially coded activities. This dynamic is especially relevant for environmental NGOs (ENGOs), which have faced considerable pressure to integrate racial equity from environmental

Blind equalization of partial discharge channels [PDF]
Zbornik Radova: Elektrotehnički Institut "Nikola Tesla"In the case of partial discharge signals, obtained during "online" monitoring or "off-line" tests of the generator, there is often interference between the direct and reflected signals or disturbances during propagation through the medium, i.e.

The Journal of Physiology, EarlyView.Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...
