1. 1. Antenna Selection and Bit Allocation Strategies for Generalized Spatial Modulation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nilab Ismailoglu; [2019]
   Keywords : ;

   Abstract : Spatial Modulation (SM) is a novel transmission technique for Multiple InputMultiple Output (MIMO) systems. In SM, a block of information bits is dividedinto two, and mapped to constellation symbols and spatial symbols. Spatialinformation is carried by the active transmit antenna index for each transmittedblock. READ MORE

3. 2. Implicit Channel Allocation in GSM/EDGE radio networks

   University essay from Institutionen för datavetenskap; Tekniska högskolan

   Author : Emily Leiviskä; [2012]
   Keywords : GSM; EDGE; GPRS packet scheduling; channel allocation; implicit channel allocation; ICA;

   Abstract : Efficient channel allocation in GSM communication is difficult and believed to be a performance bottleneck. This thesis is dedicated to studying the performance of GSM/EDGE networks in modern usage scenarios (surfing the web, chatting and streaming services) under the assumption that explicit channel allocation is not needed.

4. 3. Performance Evaluation of SpectrumSharing between LTE Femtocell andGSM Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Shen Sun; [2012]
   Keywords : ;

   Abstract : In recent years, as the data traffic demand grows rapidly, GSM spectrum refarming is emerging as one cost effective solution for operators to improve its efficiency on spectrum utilization. Among several refarming strategies, a coexistence network where LTE femtocells share the radio spectrum with the existing GSM users is regarded as one with great potential in the future practice.

5. 4. Impact and Multiplexing of SIP Signaling in GSM

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Pasha Ayani; Petter Gustafsson; [2009]
   Keywords : ;

   Abstract : By the introduction of IMS, future mobile voice traffic will gradually be based on IP. This means that GSM has to undergo further development in order to stay compatible with other mobile networks. Before introducing VoIP into GSM, the impact of the SIP signaling needs to be investigated. READ MORE

6. 5. Performance Analysis of Channel Allocation Schemes in WiMAX

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

   Author : Muhammad Rehan Usman; Johar Iqbal; Fahad Razzaq; [2009]
   Keywords : WiMAX; OFDMA; RCS; NPS; DCA; FCA; Handovers;

   Abstract : Today many cellular networks are working in parallel. For instance Global System for Mobile Communication (GSM), Universal Mobile Telecommunication System (UMTS) and Worldwide Interoperability for Microwave Access (WiMAX) etc. All of these technologies are based on cellular networks. Cellular networks are comprised of cells. READ MORE
