چکیده

-In this paper, a hit inversion (BI) procedure in previous works is furtherinvestigated over multipath frequency selective fading' channels for DS-CDMA communication systems. Moreover, after the BI procedure performed with partial parallel interference, cancellation (PPIC) schemes where the partial cancellation weight (PCW) is adapted by the least mean square (LMS) adaptive filtering algorithm, a full PIC is performed to closely cancel the multiple access interference (MAI). Simulation results show that the proposed four-stage BI-based full PIC (BI-FPIC) detector closely cancels the MA1 over a two-path frequency selective fading channel and outperforms the LMS;hased PPICschemes. :_ .

Applications of Fuzzy Logic for Adaptive Interference Canceller in CDMA Wireless Communication Systems

In this paper, the performance of the proposed fuzzy logic parallel interference cancellation (FLPIC) multiuser detector is evaluated for frequency-selective fading channels in wireless CDMA communication systems. A modified fuzzy logic system (FLS) with an adequate scaling factor (SF) is proposed to infer adequate partial factors (PFs) for the PIC scheme. Simulation results show that the propo...

An adaptive multistage parallel interference canceller for CDMA systems over Rayleigh fading channels

In direct-sequence code-division multiple-access (DS-CDMA) communication systems, the panial cancellation weight (PCW) in the partial parallel interference cancellation (PPIC) multiuser detection scheme does not give us any idea about the correctness of the bit-decision in the previous stage. Therefore, in this study, we investigate the statistical behavior of the adaptation PCW based on the le...

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
