1. 1. 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

3. 2. Nonlinear effects and predictions in advanced antenna systems in 5G Distortion Effects in 5G

   University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

   Author : Altahra Mohammed; [2019]
   Keywords : PA; DPD; Active load-pull; Calibration.;

   Abstract : In the next-generation wireless cellular communication systems known as 5G, radio equipment will be deployed in several frequency bands, among them is the millimeter wave bands (26 - 40 GHz). The use of these high frequencies can help to mitigate the limited spectrum problem and higher data rates can be achieved [2] . READ MORE

5. 4. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Advaita Advaita; Mani Meghala Gali; [2016]
   Keywords : Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

   Abstract : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.

6. 5. The Social Shaping of European Digital Radio

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Matteo Campostrini; [2015]
   Keywords : digital radio; european; europe; dab; dab ; drm; social shaping; england; uk; switzerland; sweden; italy; norway; switchover;

   Abstract : This study examines the social shaping of digital radio in Europe and provides new insights about the main competing technologies and the discourses built around their capabilities. The radio frequency spectrum is a limited resource and in order to be used in the most efficient way different organizations have been researching optimizing standards since the mid-1980s. READ MORE
