  1. 1. Ad Hoc Network Nodes Scheduling using DS and FH CDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Farhan Khan; Muhammad Umer Khan and Noman Ellahi; [2013]
    Keywords : Ad Hoc Network; Node Scheduling; FH-CDMA; DS-CDMA;

    Abstract : Nowadays most communication networks like GSM, WLan or WiMAX are based on pre-existing infrastructure. These infrastructures are complicated, costly and difficult to deploy in very short time. Whereas Wireless Ad Hoc Networks are infrastructure-free self organizing networks which consist of co-operating nodes. READ MORE

  3. 2. 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

  5. 4. PERFORMANCE ANALYSIS OF MULTIPLE ANTENNA TECHNIQUES IN WiMAX

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Yousaf Ali Shah; [2010]
    Keywords : WiMAX; Capacity Analysis; STBC; MIMO; SFBC;

    Abstract : The modern wireless systems are required to have high voice quality and data rate. Since our concern is most with cattering environment, antenna diversity is a practically effective and widely applied technique to reduce the effect of multipath fading. READ MORE

  6. 5. Comparative study of WiMAX and LTE uplink using SDCMA and LSCMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Jaswini Reddy Potuganuma; [2010]
    Keywords : Wimax; LTE uplink; physical layer; SDCMA; LSCMA; FSE; blind equalizer;

    Abstract : Blind equalizers are widely used in wireless communications for minimizing Inter Symbol Interference (ISI). The Constant Modulus Algorithm (CMA) is one of the popular blind equalizers used in broad band applications. This master’s thesis investigates the Steepest Descent Constant Modulus Algorithm (SDCMA) i.e. READ MORE
