  1. 6. Evaluating the Catching-up Process of China’s Mobile Communication Industry

    University essay from KTH/Industriell ekonomi och organisation (Inst.)

    Author : DAITIAN LI; [2011]
    Keywords : Catching-up; Leapfrogging; 3G; TD-SCDMA; Mobile industry; China; Technological capability; Market success;

    Abstract : The mobile communication technology has evolved from the first generation (1G), when the first radiotelephone service was introduced in the US in late 1940s, to the third generation (3G). In each generation, different standards and technologies were promoted by technologically and economically advanced countries. READ MORE

  3. 7. Evaluation of Word Length Effects on Multistandard Soft Decision Viterbi Decoding

    University essay from Elektroniksystem

    Author : Ahmed Salim; [2011]
    Keywords : Soft-Decision Viterbi; Tail-biting; Zero-tail; Direct Trace-back; Word Length effects; floating point quantization; BER analysis;

    Abstract : There have been proposals of many parity inducing techniques like Forward ErrorCorrection (FEC) which try to cope the problem of channel induced errors to alarge extent if not completely eradicate. The convolutional codes have been widelyidentified to be very efficient among the known channel coding techniques. READ MORE

  4. 8. Digital Predistortion for Broadcast FM repeaters

    University essay from KTH/Signalbehandling

    Author : Manne Tallmarken; [2011]
    Keywords : ;

    Abstract : This thesis presents the design and implementation of a memoryless and adaptive digital predistorter used to linearize a power amplier. Specically, it deals with the implementation of a so-called constantgain predistorter, based on a lookup table, on a digital signal processing board built around an FPGA. READ MORE

  5. 9. PERFORMANCE ANALYSIS ON MODULATION TECHNIQUES OF W-CDMA IN MULTIPATH FADING CHANNEL

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : AUN ALI TAHIR; FENG ZHAO; [2009]
    Keywords : Final Thesis as Part for Master program in Electrical Engineering with Emphasis on Telecommunication;

    Abstract : The transmission from base station to mobile or downlink transmission using M-ary Quadrature Amplitude modulation (QAM) and Quadrature phase shift keying (QPSK) modulation scheme are consider in W-CDMA system. We can analysis the performance of these modulation techniques when the system is subjected to AWGN and multipath Rayleigh fading are consider in the channel. READ MORE

  6. 10. Issues and Optimization of UMTS Handover

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Rukhsar Ahmad Cheema; Muhammad Jehanzeb Irshad; [2009]
    Keywords : UMTS handover;

    Abstract : UMTS is an emerging cell phone technology and it is basically another name for 3G mobile communication systems. It provides an enhanced range of multimedia services like video conferencing and high speed internet access. Sometimes UMTS is marketed as 3GSM emphasizing the both 3G nature and GSM standards which it was designed to succeed. READ MORE
