| Summary: | A new multicarrier direct sequence spread spectrum code division multiple access (DS-SS-CDMA) is proposed. Due to employs wavelets as orthogonal carriers to implement the filter receiver, the result shows that the new system frequency diversity of the system. By computer simulations, frequency diversity to the system by subdividing the improve the performance of the system. This new scheme it is considered to undergo the frequency selective fading, narrow band may be subjected to a flat fading which can outperforms the conventional CDMA system. the performance of the conventional CDMA which uses match the performance of this new system is evaluated. Compared to the wide bandwidth characteristic of the DS-SS-CDMA signal, transmitting bandwidth into several narrow bandwidths, each which causes severe degradation of the system. Applying |
