  1. 16. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Samiallah Shahid; Saqib Mohammad; [2013]
    Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

  3. 17. QAM and PSK Modulation Schemes under Impulsive Noise

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Ezequiel Pérez Rodenas; [2012]
    Keywords : Impulsive noise; QAM; PSK; modulation; BER; APD;

    Abstract :    Nowadays most of the communications systems are designed considering only to work under AWGN (Additive White Gaussian Noise). But the implementation of wireless systems in industrial facilities brings different kind of interference from machines or any other kind of electronic devices. READ MORE

  4. 18. 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.

  5. 19. Error Control in Wireless Sensor Networks : A Process Control Perspective

    University essay from Signaler och System

    Author : Oskar Eriksson; [2011]
    Keywords : wireless sensor networks; process control; hybrid ARQ; forward error correction; FEC; HARQ; adaptive FEC;

    Abstract : The use of wireless technology in the process industry is becoming increasingly important to obtain fast deployment at low cost. However, poor channel quality often leads to retransmissions, which are governed by Automatic Repeat Request (ARQ) schemes. READ MORE

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

    University essay from 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
