  1. 1. Synchronization Algorithms and VLSI Implementation for DC-OFDM based UWB System

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Jun Zhou; [2011]
    Keywords : UWB; OFDM; syncronization; VLSI implementation;

    Abstract : UWB is a promising technology for short-range high-rate wireless applicationa.It is able to providemaximal 480Mbps data-rate at a distance of 2 meters in realisticindoormulti-path environments. UWB technology is widely applied to the next generation WPAN as well as the wireless accessof consumer electronics at home. READ MORE

  4. 3. Peak to Average Ratio Reduction in Wireless OFDM Communication Systems

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : KAMRAN HAIDER; [2006]
    Keywords : PAR; OFDM; Active-Set; Tone reservation; PSD constraint;

    Abstract : Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today’s cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. READ MORE

  5. 4. Efficient WiMAX Receiver Implementation on a Programmable Baseband Processor

    University essay from Institutionen för systemteknik

    Author : Christian Axell; Mikael Brogsten; [2006]
    Keywords : WiMAX; OFDM; Baseband; LeoCore;

    Abstract : WiMAX provides broadband wireless access and uses OFDM as the underlying modulation technique. In an OFDM based wireless communication system, the channel will distort the transmitted signal and the performance is seriously degraded by synchronization mismatches between the transmitter and receiver.
