   Abstract : Non-orthogonal multiple access (NOMA), with its exceptional spectrum efficiency, was thought to be a promising technology for upcoming wireless communications. Physical layer security has also been investigated to improve the security performance of the system. READ MORE

4. 3. Performance Analysis of a Non-Orthogonal Multiple Access in MIMO Setup

   University essay from Blekinge Tekniska Högskola

   Author : Sankeerth Kumar Poojala; Venkata Sai Teja Vedavalli; [2021]
   Keywords : Non Orthogonal Multiple Access; NOMA; Multiple Input Multiple Output; MIMO; 5G;

   Abstract : With the advancement of wireless communication systems, the demand for higher data rates is increasing exponentially. Non Orthogonal Multiple Access (NOMA) is expected to play an important role in 5G new radio networks. In contrast to conventional multiple access schemes, NOMA allows different users to efficiently share the same resources (i.e. READ MORE

5. 4. Implementation of Spectrum Analysis Functionality for IQ-Signal.

   University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Author : Gedion Biredaw Anbessa; [2020]
   Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

   Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

6. 5. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Christina Andersen; [2020]
   Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

   Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE
