Breaking Changes

  • In LDPCBPDecoder and LDPC5GDecoder, keep_state has been replaced by stateful flag and the decoder now returns the states instead of keeping an internal reference
  • TDL and CDL power delay profiles are now normalized to have unit total power (related to issue #12).

  • Bug fix in mapping module related to double precision
  • Adds missing reference of generate_dense_polar in sionna.fec.polar.__init__
  • Improves stability of graph mode in Polar SCL decoding
  • Issue of LDPC decoding when graph is not pruned
  • Fixes missing attribute in Linear Encoder
  • Improved selection of polynomials for convolutional codes
  • Removes deprecated items in pylintrc due to updated version of Lynter
  • Typos in the documentation
  • Corrects the LoS path power calculation oft the 3GPP 38.901 channel models
  • Fixes a bug in the effective noise variance computation of the lmmse_equalizer
