slugWireless Base Station With Reduced Crest Factor
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 6
Abstract
In this paper computationally efficient signal shaping strategy is developed that can be used to substantially reduce the PAPR in multiband transmitters. In this report, we provide mathematical framework for design and analysis of PAPR reduction for multi-band transmitters. This paper addresses the problem of crest factor reduction ICFR) in multi-carrier WCDMA systems. A trade-off analysis for design and optimization of the PAPR reduction algorithm within the context of the error vector magnitude (EVMI and adjacent channel leakage ratio (ACLR) quality metrics are discussed.MC-CDMA is currently being investigated by many researchers as a promising candidate for future generations of wireless systems due to robustness to frequency selective fading, high spectral efficiency, and higher flexibility. However, the main drawback is the high Peak to Average Power Ratio (PAPR). In this paper, a method has been proposed to reduce PAPR in synchronous MCCDMA.
