The
wireless
systems with spreading
of a signal experiences time delay which has to
be smaller compar
ed to symbol period of the
data. The condition can’t be met in high data
rate transmissions which make this delay to be
greater than that of the data symbol period
which results in inter
-
symbol interference (ISI)
due to serial transmission. Therefore, a
p
erformance of pulse shaping filter for use in
WCDMA needs to
be optimized to reduce ISI for
a rate of
2Mbps. The system is simulated in
MATLAB with 16
-
QAM modulation
and
channel coding
. The error rates are determined
with
a
variation in
the
f
ilter roll off
factor (α)
.
The results have shown that the performance of
a wireless communication system depends on
the filter roll off factor. Therefore, there must
be
a
trade
-
off between filter complexity and
power efficiency in determining an optimum
roll
-
off factor which gives minimum error rate |
