  1. 21. 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
