Pilot assisted channel estimation for asymmetrically clipped optical OFDM over visible light channels
(Institute of Electrical and Electronics Engineers Inc., 2017)The Visible Light Communication(VLC) has drawn significant attention recently for wireless communication in addressing the performance limitations of wireless systems due to the scarcity of bandwidth. In VLC system the ... -
Pilot Symbol Aided Channel Estimation for Spatial Modulation-OFDM Systems and its Performance Analysis with Different Types of Interpolations
(Springer, 2017)Spatial modulation orthogonal frequency division multiplexing (SM-OFDM) system has been recently proposed as an alternative for multiple-input multiple-output (MIMO)-OFDM systems to increase spectral efficiency by keeping ... -
Pilot Symbol Assisted Channel Estimation for 4x4 Space Time Block Coded Spatial Modulation Systems
(IEEE, 2015)Recently spatial modulation (SM) and space-time block coding (STBC) are combined to take advantage of the benefits of both while avoiding their drawbacks for multiple-input and multiple-output (MIMO) systems. The pioneering ... -
Pilot-aided bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
(2004)This paper proposes a computationally efficient pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ... -
Policies of media and cultural integration in Germany: From guestworker programmes to a more integrative framework
(Sage Publications Ltd, 2014)After the arrival of the first labour migrants in Germany in the 1960s a gradual change in the perception of migrants in German politics took place: from guests (Gastarbeiter) and foreigners (Ausländer) to citizens as ... -
Political Will, Political Skill, Network Resources and Personal Reputation: A Serial Two-Mediator Model
(Sciendo, 2020)Purpose: Although social capital and positive reputation in organizations are essential for career success, there is a limited perspective in the literature on the political characteristics (motivation and ability) that ... -
Politics Policies Pronatalism and Practice: Availability and Accessibility of Abortion and Reproductive Health Services in Turkey
(Taylor & Francis Ltd, 2016)Turkey has maintained liberal contraception and abortion policies since the 1980s. In 2012 the government proposed to restrict abortion -
Polymer-Ceramic Nanocomposites
(Spie-Int Soc Optical Engineering, 2009)Steady state fluorescence (SSF) and photon transmission (PT) techniques were used for studying film formation from TiO2 and Al2O3 covered polystyrene (PS) latex particles. These films were annealed at elevated temperatures ... -
Polymer/carbon nanotube composite film formation: A fluorescence study
(Wiley-Blackwell, 2014)In this study the effect of multi-walled Carbon nanotube (MWNT) on film formation behavior of Polystrene (PS) latex film was investigated by using steady state fluorescence technique. Films were prepared by mixing of pyrene ... -
Polymorphisms at the ligand binding site of the vitamin D receptor gene and osteomalacia
(Hindawi Ltd, 2005)Vitamin D receptor (VDR) gene polymorphisms have been suggested as possible determinants of bone mineral density (BMD) and calcium metabolism. In this study our aim was to determine whether there is an association between ... -
A portable high-productivity approach to program heterogeneous systems
(IEEE, 2012)The exploitation of heterogeneous resources is becoming increasingly important for general purpose computing. Unfortunately heterogeneous systems require much more effort to be programmed than the traditional single or ... -
Positional priming of visual pop-out search is supported by multiple spatial reference frames
(Frontiers Media, 2015)The present study investigates the representations(s) underlying positional priming of visual pop-out' search (Maljkodc and Nakayama 1996). Three search items (one target and two distractors) were presented at different ... -
Positive Affect and School Related Outcomes: Feeling Good Facilitates School Engagement Among Turkish-Bulgarian Minority Adolescents
(Springer-Verlag Berlin, 2017)Fredrickson's (Rev Gen Psychol 2: 300-319, 1998, Am Psychol 56: 218226, 2001) Broaden and Build Theory (BBT) proposes that experiencing positive affect results in broadened thoughts and behaviors, which facilitate adaptive ... -
Positive effects of COVID-19 on food preparation and expenditure habits: a comparative study across three countries
(Cambridge Univ Press, 2022)Objective: This study seeks to empirically investigate how the changing eating habits affect health habits within three countries with entirely different cultures and diets to understand to what extent the pandemic may be ... -
