Member Function Documentation

int mimo::SVDDec::getDataLength (  int  codedLength  )  const [virtual]

Returns the length of an uncoded input sequence for the given length of the coded output sequence. Implements mimo::Decoder.

int mimo::SVDDec::getCodeLength (  int  rawLength  )  const [virtual]

Returns the length of a coded output sequence for a given length of the uncoded input sequence. Implements mimo::Decoder.

void mimo::SVDDec::Decode (  const CVectorSeq &  input_vectors, const MatrixFreqSignal &  channel_estimation, simth::ModSeq &  output_symbols, simth::ModSeq *  output_softout )  [virtual]

Encodes the given sequence of symbols into the given output sequence of vectors. This is the main method that has to be implemented in a derived class. Parameters: input_vectors  The received signal vectors channel_estimation  The channel matrix estimates, one for each received vector. output_symbols  The sequence of resulting output symbols output_softout  May be Null. The sequence of resulting softout reliability measures, one for each resulting output symbols. If this is Null, your implementation may not touch this. If this is non-Null, then either you have to calculate the softout values, or you have to fill this sequence with zeros. WATCH OUT: This output should contain the square root of the softout reliability information, but as complex numbers (Since 2004-11-02). The reason for this is that the Simthetic Demodulator devices expect a channel estimation input and use its squared magnitude as reliability information -- so by providing the expected values at this output interface, we can directly connect this output interface to the channel estimation input interface of the demodulator device here in simthetic. Implements mimo::Decoder.
