A theoretical investigation on exact blind channel and input sequence estimation
Ahmet Kemal Özdemir, Orhan Arıkan · 2003
Recent work on fractionally spaced blind equalizers has shown that it is possible to exactly identify the channel and its input sequence from the noise-free channel outputs. However, the obtained results are based on a set of over-restrictive constraints on the channel. In this paper it is shown that the exact identification can be achieved in a broader class of channels.
