| Summary: | 碩士 === 國立中央大學 === 電機工程研究所 === 88 === The 3th generation mobile communication system provides not only voice but also
video and data services for satisfy human request. On the premise that wideband CDMA
system becomes more improvement in the future trend. Comparisons of CDMA, TDMA
and FDMA systems, there are many advantages using CDMA in the cellular system.
The most of these advantages is increasing the system capacity. System interference will
increase by large capacity. This interference is called Multiple Access Interference ( MAI ).
In this thesis, we use Parallel Interference Cancellation Schemes to increase system
performance. We will discuss and simulate the IS-95 standard's modulator in Up-link path.
In the receiver design, we use RAKE structure to fight multipath fading and also join the
Channel Parameter Estimation to improve system performance.
Finally, according to our simulation results that the PIC technique is improving system
performance indeed.
