Abstract
We study the blind identification of single input single output
linear finite impulse response (FIR) channels via output higher-order
cumulant information. Our aim is to find simple and effective approaches
for channel estimation. The proposed algorithms identify channel impulse
response by solving a cumulant matrix pencil. Compared with several
existing linear approaches, the new methods are computationally simpler
and less sensitive to channel order over-estimation. We also present
simulation results that demonstrate the robustness of the new methods to
various channel conditions in practical applications
