1. 1. 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

   Abstract : As part of an ongoing project at the department of electrical engineering, ISY, at Linköping University, a voice decoder using floating point formats has been the focus of this master thesis. Previous work has been done developing an mp3-decoder using the floating point formats. All is expected to be implemented on a single DSP. READ MORE

4. 3. Design and implementation of test a tool for the GSM traffic channel.

   University essay from Institutionen för systemteknik

   Author : Theo Öjerteg; [2002]
   Keywords : Datorteknik; GSM; speech codec; traffic generation; test tool; test automation; DSP; telecommunication; TSS; encoder; decoder; Datorteknik;

   Abstract : Todays’ systems for telecommunication are getting more and more complex. Automatic testing is required to guarantee quality of the systems produced. An actual example is the introduction of GPRS traffic in the GSM network nodes. This thesis investigates the need and demands for such an automatic testing of the traffic channels in the GSM system.
