  1. 1. Quantization Effects Analysis on Phase Noise and Implementation of ALL Digital Phase Locked-Loop

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jue Shen; [2011]
    Nyckelord :All Digital Phase-Locked Loop ADPLL ; Quantization Step; Non-linear quantization effect; Non-linear PLL noise model; Phase Noise; Matlab Modeling; Verilog Behavior Modeling.;

    Sammanfattning : With the advancement of CMOS process and fabrication, it has been a trend to maximize digital design while minimize analog correspondents in mixed-signal system designs. So is the case for PLL. PLL has always been a traditional mixed-signal system limited by analog part performance. LÄS MER

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

    Master-uppsats, Elektroniksystem

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

    Sammanfattning : 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. LÄS MER
