+	* doc/tutorial/demapper_mimo.doc, doc/tutorial/sources.mk,
+	  doc/tutorial/src/Makefile.am, 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.

+
+	* itpp/base/vec.h: initialization of local variable in order to
+	  close bug ID: 3425833
+
+2011-11-20  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>
+
+	* 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  <erik_g_larsson@users.sourceforge.net>
+
+	* itpp/comm/error_counters.h, itpp/comm/error_counters.cpp: Minor

+
+2011-11-06  Bogdan Cristea <cristeab@users.sourceforge.net>
+
+        * itpp/comm/siso_dem.cpp: corrected Alamouti_maxlogMAP. Thanks to

+
+	* 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  <erik_g_larsson@users.sourceforge.net>
+
+	* 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  <erik_g_larsson@users.sourceforge.net>
+
+	* 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.
