1. 46. Performance Analysis of Selected Cooperative Relaying Techniques

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Muhammad Afaq; Sahibzada Muhammad Faheem; [2010]
   Keywords : Cooperative communication; Relaying techniques; Amplify-and-forward; Decode-and-forward; DtF; S-DtF; MRC;

   Abstract : Recently, cooperative communication has gained significant interest due to the fact that it exploits spatial diversity and provides capacity/performance gain over conventional single- input single-output (SISO) systems. A mobile node with single antenna can cooperate with a nearby mobile node having single antenna in multi-user environment to create the effect of virtual multiple antenna system. READ MORE

3. 47. PERFORMANCE EVALUATION OF LTE DOWNLINK WITH MIMO TECHNIQUES

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Mengistu GESSESE; Olayinka OLADELE; [2010]
   Keywords : 3GPP LTE; 16QAM; 64QAM; EPS; ITU-B; MIMO; OFDM; OFDMA; SCFDMA; SSD; UMTS; ZF;

   Abstract : Long Term Evolution (LTE) of the Universal Mobile Telecommunication System (UMTS) also known as the Evolved Packet System (EPS) is a transilient move in the field of mobile communications. Such a revolution is necessitated by the unceasing increase in demand for high speed connections on networks, low latency and delay, low error rates and resilience because modern users and network applications have become increasingly dependent on these requirements for efficient functionality and performance.

4. 48. COOPERATIVE COMMUNICATION TECHNIQUES IN WIRELESS NETWORKS (ANALYSIS WITH VARIABLE RELAY POSITIONING)

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Danna Nigatu Mitiku; Onwuli Chinedu Lawrence; [2010]
   Keywords : Amplify-and-Forward; Bit-Error-Rate; Cooperative Communications; Decode and Forward; Performance Analysis; Signal-to-Noise-Ratio; Wireless Networks;

   Abstract : Signal transmission in Wireless Networks suffers considerably from many impairments, one of which is channel fading due to multipath propagation. Cooperative communication is a technique which could be employed to mitigate the effects of channel fading by exploiting diversity gain achieved via cooperation between nodes and relays. READ MORE

5. 49. Transmitter Macrodiversity in Multihop Sensor Networks

   University essay from Institutionen för informationsteknologi och medier

   Author : Munawar Saeed; [2009]
   Keywords : Single Frequency Networks; SFN; Matlab; sensor networks; macro-diversity; multihop routing; DSFN; OFDM;

   Abstract : Wireless Sensor Network is an emerging technology that has applicationsin Wireless Actuators, remote controlling, distribution of softwareupdates and distribution of parameters to sensor nodes. This projectwork basically covers the concept of macro-diversity. READ MORE

6. 50. PERFORMANCE ANALYSIS OF ADAPTIVE ARRAY SYSTEM AND SPACE-TIME BLOCK CODING IN MOBILE WIMAX (802.16e) SYSTEMS

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Author : Ngan Trieu Kim; Olumide Ajiboye; [2008]
   Keywords : WiMAX; 802.16e; Adaptive Antenna System ; Beamforming; MIMO; Space Time Coding ; AAS; STC;

   Abstract : We live in an information hungry age, we generate and process information at a rate never before recorded in the history of mankind. Today’s computing platforms are run on Gigahertz multi-core processors churning out Gigabits streams of data that need to be transmitted as quickly as possible. READ MORE
