| סיכום: | In this paper two proposed schemes for improving the performance form the
Bit Error Rate (BER) view point were proposed for Multicarrier-Direct-Sequence-
Code Division Multiple Access (MC-DS-CDMA) system in wireless channel. The
conventional MC-DS-CDMA-system is based on Fast Fourier Transform (FFT). One
of the proposed systems was based on Wavelet transform (WT). The other system was
based on Slantlet transform (SLT). Simulation is done in three different types of
channels. Simulation results show that the two proposed systems outperform the
conventional system. Also the MC-DS-CDMA-system which is based on SLT achieves
the same performance with less filter lengths than the MC-DS-CDMA-system based on
WT. |
