Revision as of 15:19, 16 August 2008 edit 117.192.104.251 (talk) No edit summary ← Previous edit		Revision as of 01:06, 24 October 2008 edit undo 98.243.65.184 (talk) Hx = Hy does not imply x = y (this is obvious since if x and y are both codewords then Hx = Hy = 0, but equivalent errors will also give the same syndrome) Next edit →
Line 107: :<math>x = z - e </math> ~~Notice that this will always give a unique (but not necessarily accurate) decoding result since~~ ~~: <math>Hx = Hy</math>~~ if and only if <math>x=y</math>. This is because the parity check matrix <math>H</math> is a generator matrix for the dual code <math>C^\perp</math> and hence is of full [[rank (linear algebra)\|rank]]. == Partial response maximum likelihood ==
