of the phantom sources and further treatmcnt to the
pliantoni sources requires knowledge of the number of
active sourcesl which might not be available in pratice.
By the introduction of the SSCL algorithm, not only
has the problem of phantom sources been overcome but
also the algorithm is able to operate in a complete blind
sense. The requircnient of knowing the number of active
sources bas been eliminated. Siniulations results
