Abstract
A subspace training method has been proposed for
dispersive direct-sequence code division multiple access (DS-CDMA) channels.
Its performance was compared to a matched filter receiver. We think that it is
not quite fair to compare a minimum mean square error (MMSE) based receiver to
a matched filter receiver. For this reason, we further investigate the method
demonstrating that its performance significantly falls short of the true MMSE
receiver and that it suffers from error floor. We also illustrate that any attempt
to fill the gap significantly increases the system complexity and drops the
efficiency of the transmission, which were originally mentioned as the
advantages of the proposed method.
