3. 2. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Hassan Sajjad; Muhammad Jamil; [2012]
   Keywords : Signal Processing; Fading Channel; Multi-hop;

   Abstract : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

4. 3. ANALYSIS, IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF A PHASE SHIFTED PWM CONTROL SYSTEM FOR A MODULAR MULTILEVEL CONVERTER

   University essay from KTH/Elektrisk energiomvandling

   Author : Juan Colmenares; [2011]
   Keywords : ;

   Abstract : Nowadays, it is problematic to connect only one power semiconductor switch directly to the grid due to the high voltage range. In order to solve this difficulty, a new type of power converter has been introduced as a solution in high power applications. READ MORE

5. 4. 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.
