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

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

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

    Abstract : 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. READ MORE

  3. 2. 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
