    Sammanfattning : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. LÄS MER

  7. 5. 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
