The use of orthogonal frequency division multiplexing in high-bit-rate communication systems is appealing. Due to its fast data rate, resilience to delay spread, frequency spectrum efficiency, and other features, it has been widely utilised in current wireless communication. In addition to these benefits, a significant disadvantage of OFDM is the high Peak-to-average-power ratio (PAPR) of the transmitter's output signal, which limits the system's performance. The Iterative Clipping and Filtering (ICF) approach is used in this case because it yields better results than the Clipping method, which is the easiest way to lower the PAPR of the OFDM system. Another strategy that effectively reduces PAPR is selective mapping (SLM), in which the actual transmit signal is chosen from a list of candidates.

“…The exponentially increasing complexity of the PTS scheme prevents its use for MC-CDMA. Kang et al (Kang et al;2005) propose an efficient PTS scheme through phase factor optimization to reduce the complexity. Natarajan et al 2004) address signal compactness issues in MC-CDMA employing CI codes using the measure of crest factors.…”

“…In addition to clipping method, other methods like Successive clipping and filtering, Precoding, Partial Transmit Sequences (PTS) for PAPR reduction in MC-CDMA system are analyzed in (Ginige et al, 2001;Kang et al, 2005) In PTS method, parallel inputs to IFFT/FFT block are portioned into smaller parts and multiplied by sequences which are selected to reduce PAPR which produces multicarrier signal with low PAPR after IFFT/FFT process and transmitted.…”

Problem statement: Multi Carrier Code Division Multiple Access (MC-CDMA), a promising technology for the 4G communication systems. The major limitation of MC-CDMA system is the Multiple Access Interference (MAI) which is due to near-far effect, frequency offset and nonlinear power amplification due to clipping noise. Approach: The performance of MC-CDMA under clipping noise using Global search algorithm based Multiuser detector in AWGN, Rayleigh and Rician channel is analyzed in this study. Results: The proposed method is simulated using BPSK modulation, Walsh spreading code, number of subcarriers 64 and number of users 16 and clipping noise. Conclusion: By simulation result, BER in AWGN channel outperforms other channels as SNR is increased. The performance of Rician fading channel is better than that of Rayleigh fading channel, because of the LOS path.
