	* doc/tutorial/demapper_mimo.doc, doc/tutorial/,
	  doc/tutorial/src/, doc/tutorial/src/demapper_mimo.cpp,
	  itpp/comm/siso.h: added explanations about the overlap in
	  functionality between the SISO class and the Modulator_ND class.
	  Added an usage example for SISO demappers when using ST codes in
	  MIMO channels.

2011-11-25  Bogdan Cristea <>

	* itpp/base/vec.h: initialization of local variable in order to
	  close bug ID: 3425833

2011-11-20  Erik G. Larsson  <>

	* itpp/comm/ldpc.h, itpp/comm/ldpc.cpp: New function for soft
	syndrome check calculation in the LDPC class

2011-11-20  Erik G. Larsson  <>

	* itpp/comm/error_counters.h, itpp/comm/error_counters.cpp: Minor
	feature enhancement in the error counter classes

2011-11-06  Bogdan Cristea <>

        * itpp/comm/siso_dem.cpp: corrected Alamouti_maxlogMAP. Thanks to
	tytusz for pointing this bug

2011-09-15   Erik G. Larsson  <>

	* itpp/base/gf2mat.cpp: Fixed assertion in
	GF2mat_sparse_alist::read().  This closes bug report #3408884.
	Thanks to Laurent Schmalen for providing the patch.

2011-06-02   Erik G. Larsson  <>

	* itpp/comm/ldpc.h, itpp/comm/ldpc.cpp: Added the possibility to
	disable integrity checking when initiating an LDPC code. This
	closes feature request #3309430.  Thanks to Laurent Schmalen for
	providing the patch.

2011-05-19   Erik G. Larsson  <>

	* itpp/comm/ldpc.cpp: Fixed a bug in the LDPC decoder, that occurs
	in the special case of a lonely variable node (i.e. a variable
	node that is connected to only one check node) in the LDPC
	decoder. The incoming C->V message was missing in the outgoing LLR
	value. This special case is very rare but apparently occurs for
	some codes in the DVB-T2 standard.  We thank Gorka Agujeta and
	Daniel Ansorregui for pointing out this error.

2011-05-05  Bogdan Cristea  <>

	  tests/stc_test.ref: changed STC interface, added error checking
	  using it_assert()

2011-02-21  Bogdan Cristea  <>

	* itpp/comm/stc.cpp, itpp/comm/stc.h, tests/stc_test.cpp: added
	  more error checking on input parameters

2011-02-20  Bogdan Cristea  <>

	* tests/stc_test.cpp, win32/itpp_acml_tests/itpp_acml_tests.sln,
	  win32/itpp_mkl.sln, win32/itpp_mkl_tests/itpp_mkl_tests.sln:
	  added tests for Visual Studio projects, corrected minor error in

2011-02-20  Bogdan Cristea  <>

	* itpp/comm/stc.cpp, itpp/comm/stc.h, tests/,
	  tests/stc_test.cpp, tests/stc_test.ref: Corrected error in STC
	  class when generating V-BLAST code. Simplified STC interface.
