Limited Feedback for 3D Massive MIMO under 3D-UMa and 3D-UMi Scenarios
International Journal of Antennas and Propagation, 2015 For three-dimensional (3D) massive MIMO utilizing the uniform rectangular array (URA) in the base station (BS), we propose a limited feedback transmission scheme in which the channel state information (CSI) feedback operations for horizontal domain and ...

Analysis and improvement of the vector quantization in SELP (Stochastically Excited Linear Prediction) [PDF]
The Stochastically Excited Linear Prediction (SELP) algorithm is described as a speech coding method employing a two-stage vector quantization. The first stage uses an adaptive codebook which efficiently encodes the periodicity of voiced speech, and the ...

Circular Economy Pathways for Airport Climate Change Mitigation
Business Strategy and the Environment, EarlyView.ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

Codebook Generation Using Partition and Agglomerative Clustering
Advances in Electrical and Computer Engineering, 2011 In this paper, we present a codebook generation algorithm to produce a codebook with lower distortion. Our method combines a fast codebook generation algorithm (CGAUCD) with doubling technique and fast agglomerative clustering algorithm (FACA) to ...
