Telecommunication capable of handling interference, fading and no less important
issues regarding the confidentiality of user information is very much needed in the current
technological era, to overcome this spread spectrum technology is quite developed in the
advancement of telecommunication technology. In this study, the small kasami code was used
as the spreading code. The purpose of this study is to determine the performance of the small
kasami code with changes in the number of multipath components using multipath fading
channels. The modulation technique uses digital modulation, namely binary phase shift keying
(BPSK) with a small kasami code with a code length of 15 in the spreading and spreading
process. Analyzed based on BER (Bit Error Rate) versus EB/No (Energy Bit per Noise). In the
simulation of flat fading performance using 1 multipath component, flat fading serves as an ideal
reference where the simulation BER should resemble the theoretical BER as simulation
validation so that it can be used on selective fading channels. Variation of multipath
components in frequency selective fading channel produces different BER because there is
interference of multipath signal to the desired signal. The number of multipath components as
many as 11 have the most interference signals resulting in the worst performance. The value of
cross correlation between users has poor performance, where the correlation value of user 1
with 2, 3, and 4 is more than 0, this value shows that many signal levels experience interference
between users.
