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

   Author : Shabai He; [2012]
   Keywords : time dispersion channels; intersymbol interference; adaptive equalization;

   Abstract : The new released 4G standard wireless communication reminds us that higher transmission data rate and more reliable service are required urgently. However, to fulfill the demand can face problems in a complex environment like mines. READ MORE

3. 22. Measurement and Analysis of Radio Wave Coverage in Industrial Environments

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Per Ängskog; [2012]
   Keywords : radio propagation; radio coverage; industrial environment; measurement system; radio measurement; path loss;

   Abstract : Several studies have characterized the path loss properties in industrial environments. However most of them have focused on one frequency, and some two or maximum three frequencies, usually cellular telephone frequencies or the unlicensed ISM bands that are commonly used in various industries.

4. 23. Comparision between single mesh network and cell-based mesh network

   University essay from JTH, Data- och elektroteknik

   Author : Manish Timilsina; [2012]
   Keywords : Cell-based network;

   Abstract : The theme of this thesis is to analyse the performance of a conventional mesh topology in a multipath fading environment and compare it with a newly proposed multiple cell based mesh topology. The communication performance in general is measured by the overall through-put, packets delivery reliability, average message delivery delay and power-consumption. READ MORE

5. 24. Channel estimation in mobile wireless systems

   University essay from KTH/Signalbehandling

   Author : Pazi Alli Idd; [2012]
   Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

   Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.
