  Like other pseudorandom sequences, decimal sequences may be used in designing
a Code Division Multiple Access (CDMA) system. They appear to be ideally suited
for this since the cross-correlation of d-sequences taken over the LCM of their
periods is zero. But a practical system will not, in most likelihood, satisfy
the condition that the number of chips per bit is equal to the LCM for all
sequences that are assigned to different users. It is essential, therefore, to
determine the partial cross-correlation properties of d-sequences. This paper
has performed experiments on d-sequences and found that the partial
cross-correlation is less than for PN sequences, indicating that d-sequences
can be effective for use in CDMA.
