  1. 41. Implementation of MIMO-OFDM System for WiMAX

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

    Author : Muhammad Atif Gulzar; Rashid Nawaz; Devendra Thapa; [2011]
    Keywords : MIMO; OFDM; WiMAX;

    Abstract : Error free transmission is one of the main aims in wireless communications. With the increase in multimedia applications, large amount of data is being transmitted over wireless communications. This requires error free transmission more than ever and to achieve error free transmission multiple antennas can be implemented on both stations i.e. READ MORE

  3. 42. Distributed gateways for terabit/s satellite : Study of smart gateway diversity

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

    Author : Florian Romain Gain; [2011]
    Keywords : ;

    Abstract : Future Satcom systems will be required to provide Internet at high capacity to an increasing number of users. Because of demanding applications the throughput should approach the Tb/s. To achieve such a data rate, large bandwidths are required. So considering spectrum congestion below 15 GHz, communications should use Ka and Q/V bands. READ MORE

  4. 43. Performance Analysis of DF Relay Systems with Keyhole and Correlation Effects

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Rajendra Dhakal; Sagar Raj Mahat; [2011]
    Keywords : Correlated channel; decode-and-forward; keyhole effects; moment generating function; orthogonal space-time block codes; symbol error rate;

    Abstract : In recent years, the innovation of multiple-input multiple-output (MIMO) has completely changed the face of wireless communication system. Especially, the concept of MIMO is evolved to fulfill the demand of multimedia services. READ MORE

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

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

    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

  6. 45. DETECTION OF VACANT FREQUENCY BANDS IN COGNITIVE RADIO

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ahmed Rehan; Ghous Yasir Arfat; [2010]
    Keywords : Cognitive radio; Spectrum Sensing ; Vacant Frequency bands; Spectrum Hole; Spectrum mobility; Cooperation strategies;

    Abstract : Cognitive radio is an exciting promising technology which not only has the potential of dealing with the inflexible prerequisites but also the scarcity of the radio spectrum usage. Such an innovative and transforming technology presents an exemplar change in the design of wireless communication systems, as it allows the efficient utilization of the radio spectrum by transforming the capability to dispersed terminals or radio cells of radio sensing, active spectrum sharing and self-adaptation procedure.
