1. 1. Pilot Contamination and Mitigation Techniques in Massive MIMO Systems

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Vidit Saxena; [2014]
   Keywords : Multicell Systems; Massive MIMO; Pilot Contamination; LTE; Power Control; Resource Allocation; Channel Estimation; Precoding; Technology and Engineering;

   Abstract : A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. READ MORE

3. 2. Study of inter-cell interference and its impact on the quality of video conference traffic in LTE Network

   University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

   Author : MD. Jhirul Islam; Mohammed Nazmul Haider Chowdhury; [2013]
   Keywords : LTE; Inter-cell Interference; Video Conferencing; OPNET.;

   Abstract : While inter-cell interference coordination (ICIC) for the downlink and uplink of multi-cell systems (in general) and orthogonal frequency division multiple access (OFDMA) networks (in particular) have been extensively studied, the study of the impact caused by inter-cell interference with video conferencing traffic has received less attention. The consideration of video conferencing traffic is essential for analyzing the overall performance analysis of inter-cell interference in LTE networks, and in particular for the evaluation of the video conferencing traffic.

4. 3. Realistic Multi-Cell Interference Coordination in 4G/LTE

   University essay from Kommunikationssystem; Tekniska högskolan

   Author : Sara Örn; [2012]
   Keywords : link adaptation; interference estimation; coordinated scheduling; LTE; 4G; radio resource management;

   Abstract : In the LTE mobile system, all cells use the same set of frequencies. This means that a user could experience interference from other cells. A method that has been studied in order to reduce this interference and thereby increase data rate or system throughput is to coordinate scheduling between cells. READ MORE

5. 4. Frequency Hopping in LTE Uplink

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Author : Tariku Temesgen Mehari; [2009]
   Keywords : Frequency Hopping; LTE Uplink; RRM; Scheduling;

   Abstract : In the 3GPP LTE, different radio resource management (RRM) techniques have been proposed in order to improve the uplink performance. Frequency hopping is one of the techniques that can be used to improve the uplink performance by providing frequency diversity and interference averaging. READ MORE
