Peak to Average Power Ratio Reduction Techniques for Long Term Evolution- Single Carrier Frequency Division Multiple Access System
As the power consumption is an essential issue for designers of mobile devices The 3 Generation Partnership Project (3GPP) – Long Term Evolution (LTE) employs a multicarrier communication technique on the air interface, Single Carrier Frequency Division Multiple Access (SCFDMA), in uplink scenario and Orthogonal Frequency Division Multiple Access (OFDMA) in the downlink. SCFDMA core modulation ...
متن کاملPrototype of a Peak to Average Power Ratio Reduction Scheme in Orthogonal Frequency Division Multiplexing Systems
Peak to average power ratio (PAPR) is one of the main imperfections in the broadband communication systems with multiple carriers. In this paper, a new crest factor reduction (CFR) scheme based on interleaved phase sequence called Dummy Sequence Insertion Enhanced Partial Transmit Sequence (DSI-EPTS) is proposed which effectively reduces the PAPR while at the same time keeps the total complexit...
متن کاملPeak to Average Power Ratio reduction method for Orthogonal Frequency Division Multiplexing in 4G Communication
Recent development in data communication applications, the role of Orthogonal Frequency Division Multiplexing (FDM) technology is unavoidable. The OFDM system improves the multipath fading channel and bandwidth in effective manner. But the main problem in OFDM is large fluctuations. This often affected the design performance and produces the poor results when compared to the existing methodolog...
متن کاملLow-complexity peak-to-average power ratio reduction method for orthogonal frequency-division multiplexing communications
The high peak-to-average power ratio (PAPR) of the transmitted signal is a major drawback of multicarrier transmission such as orthogonal frequency-division multiplexing OFDM. A plethora of PAPR reduction techniques has been reported in the literature. Some of the techniques modify the phase and/or amplitude of symbols in the original symbol alphabet (SA) such as selected mapping and partial tr...
متن کاملApplication of PSO Optimized Companding in Peak Average To Power Ratio(PAPR) Reduction In Orthogonal Frequency Division Multiplexing(OFDM)
Orthogonal frequency division multiplexing (OFDM) modulation using orthogonal subcarriers reduces the delay spread by increasing robustness to multipath fading and can use overlapped bandwidth due to orthogonality on frequency domain. The main drawback of Orthogonal Frequency Division Multiplexing(OFDM) systems is the high peak-to average power ratio (PAPR),which significantly reduces the effic...
