  5. 39. Performance Evaluation of TCP Variants over UMTS Networks

    University essay from Institutionen för informationsteknologi

    Author : Nikunj Modi; [2008]
    Keywords : ;

    Abstract : With the evolution of 3G technologies like Universal Mobile TelecommunicationSystem (UMTS), the usage of TCP has become more popular for a reliable end-to-end (e2e) data delivery. However, TCP was initially designed for wired networks and therefore it suffers performance degradation due to the radio signal getting affected by fading, shadowing and interference. READ MORE

  6. 40. DATA PROCESSING DESIGN OF WIDEBAND CODE DIVISION MULTIPLE ACCESS (WCDMA)

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : THUMATI VENKATA RAO; [2007]
