PAPR Reduction of an MC-CDMA system using SLM technique
Multicarrier Code Division Multiple Access is the most promising technique for high speed data transmission. However, the MC-CDMA signals are characterized by large peak to average power ratios (PAPR), which can reduce the system efficiency. In this paper PAPR reduction of an MCCDMA system using SLM technique is investigated for different modulation schemes. The binary phase sequences considere...
متن کاملOverview of MC CDMA PAPR Reduction Techniques
High Peak to Average Power Ratio (PAPR) of the transmitted signal is a critical problem in multicarrier modulation systems (MCM) such as Orthogonal Frequency Division Multiplexing (OFDM), and Multi-Carrier Code Division Multiple Access (MC CDMA) systems, due to large number of subcarriers. High PAPR leads to reduced resolution, and battery life. It also deteriorates system performance. This pap...
متن کاملMC CDMA PAPR Reduction Techniques using Discrete Transforms and Companding
High Peak to Average Power Ratio (PAPR) of the transmitted signal is a serious problem in multicarrier modulation systems. In this paper a new technique for reduction in PAPR of the Multicarrier Code Division Multiple Access (MC CDMA) signals based on combining the Discrete Transform either Discrete Cosine Transform (DCT) or multi-resolution Discrete Wavelet Transform (DWT) with companding is p...

متن کاملPerformance analysis of PAPR reduction techninques for MC-CDMA system
MC-CDMA and OFDM systems are widely used in the existing 3rd and 4th generation wireless networks. They are also good candidates for the future generation networks for broadband and personal communications. But, high peak to average power ratios (PAPR) is serious problem in MCCDMA which can increase complexity in the analog to digital and digital to analog converter, reduce the system efficienc...
