Detailed Description

Implementation of a linear Mimimum-Mean-Square-Error (MMSE) equalizer/decoder for a Spatial Multiplexing system (this is mostly the same as V-BLAST). At high SNR, this simply multiplies the received vectors with the matrix inverse of the channel transfer matrix. At lower SNRs, the formula is slightly different.

void mimo::SpatialMuxDecMMSE::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. Reimplemented from mimo::SpatialMuxDecZF.

void mimo::SpatialMuxDecMMSE::setSNR (  double  snr  )

Sets the signal-to-noise ratio to 'snr', while the signal power is kept constant.
