virtual void simthlib::DiffSubSeqDemodulatorMetric::adachiDemodulate (  const simth::ModSeq &  receivedSym, simth::LlvSeq *  correspondingLlvValues1, simth::LlvSeq *  correspondingLlvValues2, double  noise = 0, const simth::ModSeq *  trans = NULL )  [virtual]

See "Viterbi-Decoding Differential Detection of DPSK", Adachi, Electronic Letters 1992, Vol. 28 No. 23 Reimplemented from simthlib::DiffDemodulatorMetric.

virtual void simthlib::DiffSubSeqDemodulatorMetric::demodulate (  const simth::ModSeq &  receivedSym, simth::LlrSeq *  correspondingLlrValues, double  noise = 0, const simth::ModSeq *  trans = NULL )  [virtual]

Demodulates a sequence of received data words to a sequence of log-likelihood-ratio (llr) values; each simth::LLR_-value represents the hard decisions of one bit and the probability of this decision. The hard decision (the bit itselfs) is determined by the sign of the simth::LLR_-Value, whereas the probability is described by the absolute value of the log-likelihood ratio: /f$llr = ln(p(1)/p(0))/f$ Reimplemented from simthlib::DiffDemodulatorMetric.

virtual void simthlib::DiffSubSeqDemodulatorMetric::demodulate (  const simth::ModSeq &  receivedSym, simth::LlvSeq *  correspondingLlvValues, double  noise = 0, const simth::ModSeq *  trans = NULL )  [virtual]

Demodulates a sequence of received data words to a sequence of log-likelihood-values (llv). Reimplemented from simthlib::DiffDemodulatorMetric.

virtual void simthlib::DiffSubSeqDemodulatorMetric::print (  std::ostream &  os  )  const [virtual]

Reimplemented from simthlib::DiffDemodulatorMapping. Reimplemented in simthlib::DpskDemodulator, simthlib::DpskDemodulatorQC, simthlib::DpskDemodulatorDD, simthlib::DpskDemDD_STD, simthlib::DpskDemDD_AWGN, simthlib::DpskDemDD_MIN, simthlib::DpskDemDD_KARSTEN, simthlib::DaskDemodulator, simthlib::DaskDemodulatorQC, simthlib::DaskDemodulatorDD, and simthlib::DaskDemDD_STD.
