Member Function Documentation

int simthlib::SoftoutDAPSKDecoding::bitsPerAmpl (   )  const [inline, protected]

int simthlib::SoftoutDAPSKDecoding::bitsPerPhase (   )  const [inline, protected]

virtual int simthlib::SoftoutDAPSKDecoding::codedBitsPerStep (   )  const [inline, virtual]

Returns the coded output bits per step of the associated encoder, i.e. the number of input bits per step of this decoder. Implements simthlib::StreamSoftoutDecoding.

void simthlib::SoftoutDAPSKDecoding::computeSplittedSizes (  int  numInSize, int *  amplSize, int *  phaseSize )  const [protected]

virtual int simthlib::SoftoutDAPSKDecoding::dataBitsPerStep (   )  const [inline, virtual]

Returns the number of uncoded data input bits per step of the associated encoder, i.e. the number of data output bits per step of this decoder. Implements simthlib::StreamSoftoutDecoding.

virtual int simthlib::SoftoutDAPSKDecoding::getCodeLength (  int  rawLength  )  const [virtual]

Returns the length of the coded bit sequence which the coder generates from a data sequence of the given length. Implements simthlib::SoftoutDecoding.

virtual int simthlib::SoftoutDAPSKDecoding::getDataLength (  int  codedLength  )  const [virtual]

Returns the length of a data bit sequence which can be encoded into a coded bit sequence of the given length. Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::normalDecoding (  const simth::LlrSeq &  llr, simth::BitSeq &  bsout )  [virtual]

Performs a maximum likelihood sequence estimation of the data sequence based on the log-likelihood ratios of the received modulation symbols (soft decision decoding without soft {out}put) This can be usefull in the last step of an iterative decoding procedure when no soft-out information is needed. Implements simthlib::SoftoutDecoding.

virtual size_t simthlib::SoftoutDAPSKDecoding::numTailbits (   )  const [inline, virtual]

Implements simthlib::StreamSoftoutDecodingTailbits.

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

Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::reset (   )  [virtual]

Since this class does not store any data when processing a decoding function that will be used by following decoding functions, this class uses the (empty) standard implementation given by the base class SoftOutDecoding. Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::softout4InputBits (  simth::LlrSeq &  metr, simth::LlrSeq *  softout, simth::LlrSeq *  apri = NULL )  [virtual]

Estimates soft output for the given coded sequence of llrValues. Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::softout4InputBits (  simth::LlvSeq &  metr, simth::LlrSeq *  softout, simth::LlrSeq *  apri = NULL )  [virtual]

Estimates soft output for the given coded sequence of llvValues. Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::softout4OutputBits (  const simth::LlrSeq &  metr, simth::LlrSeq *  softout, simth::LlrSeq *  apri = NULL )  [virtual]

Estimates soft output for the output sequence of the decoder (resp.\ the data sequence) due to the given input sequence of llrValues. Implements simthlib::SoftoutDecoding.

virtual void simthlib::SoftoutDAPSKDecoding::softout4OutputBits (  const simth::LlvSeq &  metr, simth::LlrSeq *  softout, simth::LlrSeq *  apri = NULL )  [virtual]

Estimates soft output for the output sequence of the decoder (resp.\ the data sequence) due to the given input sequence of llvValues. Implements simthlib::SoftoutDecoding.
