  1. 1. Performance Evaluation of LTE Physical Layer Using SC-FDMA & OFDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abdul Samad Shaikh; Khatri Chandan Kumar; [2011]
    Keywords : OFDMA; SC-FDMA; LTE; BER; PAPR;

    Abstract : Since past few decades different types of cellular networks were launched and went successful on the radio links such as WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services. READ MORE

  2. 2. On Models for Interference Calculations between Radio Communication Systems

    University essay from KTH/Signalbehandling

    Author : Fredrik Vihlborg; [2011]
    Keywords : ;

    Abstract : When installing a new radio system, it is of great importance to know that it will not interfere with the already existing systems, and that they can coexist side by side. The problems that will follow if interference occurs, can be of huge magnitude, e.g. radars not working, trains stopping etc. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; 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.
