Star Student Project
estimated channel impulse responses (CIRs) for the distributed two-user system.
It is obvious from the iteration goes on, the CIRs look like MUI-free ones,
which verifies the effectiveness of the MUI cancellation in the SUD-based receiver.
The constellation scattering plots the soft-decision symbols at the output of
the MMSE detector for users 1 and. The improvement over iterations is clearly
observed by comparing subfigures in each row. Star Student Project can see that during the startup stage, the
CIRs and scatter plots for both users look very noisy due to the severe MUI, as
expected.
