Member Function Documentation

virtual void simthlib::ReedSolomonDecoder::decode (  const simth::LlvSeq &  llr, simth::BitSeq &  bsout )  [virtual]

Performs a maximum likelihood sequence estimation of the data sequence based on the log-likelihood values of the given (the received) modulation symbols (soft decision decoding) Implements simthlib::Decoder.

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

Performs a maximum likelihood sequence estimation based on the log-likelihood ratios given by the demodulator (the received modulation symbols) (soft decision decoding). Implements simthlib::Decoder.

virtual void simthlib::ReedSolomonDecoder::decode (  const simth::BitSeq &  llr, simth::BitSeq &  bsout )  [virtual]

Decodes a bit sequence (hard decision decoding). Implements simthlib::Decoder.

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

Returns the length of a coded bit sequence which is generated by the coder from a raw data sequence of the given length. Parameters: rawLength  length of the data sequence Returns: allocated length of the coded sequence Implements simthlib::Decoder.

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

Returns the length of a data bit sequence which is encoded by the coder from a coded bit sequence of the given length Parameters: codedLength  length of the coded sequence Returns: allocated length of the encoded data sequence Implements simthlib::Decoder.

virtual void simthlib::ReedSolomonDecoder::updateInputLengths (   )  [virtual]

Implements simth::Device.

virtual void simthlib::ReedSolomonDecoder::updateOutputLengths (   )  [virtual]

Implements simth::Device.
