Reducing the peak to average power ratio in OFDM systems
High peak to average power ratio of the transmit signal is a major drawback of OFDM systems. After defining the PAPR and analyzing its statistical properties, some of the most representative PAPRreduction techniques available in the literature are reviewed in detail. Several methods have been proposed to reduce the peak power of OFDM signals. In this paper the effectiveness of some recently pro...
متن کاملInvestigating of The Reducing Techniques for The Peak to Average Power Ratio(PAPR) in OFDM Systems
High Peak to Average Power Ratio (PAPR) for OFDM system is still a demanding area and difficult issue. The radio transmitter stations for covering and getting enough transmit power in their desired area have to use High Power Amplifier (HPA). On the other hand, in order the HPA have the most output power efficiency must be designed to work close to the saturation region therefore due to the hig...

متن کاملImproved Clipping Technique for Reducing the Peak to Average Power Ratio in OFDM Systems
Peak to Average Power Ratio (PAPR) is one of the disadvantages of OFDM system, which had been studied in several papers and reduced in several techniques. Clipping and filtering are an effective technique for reducing the PAPR in OFDM systems. It requires an accurate filtering to reduce the resulting in-band and out-ofband noise. In this paper, an improved clipping technique is proposed. The te...
متن کاملPeak to Average Power Ratio Reduction for Mimo-ofdm Systems with Decomposed Selected Mapping
A major drawback of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems is its high peak-to-average power ratio (PAPR). A decomposed selected mapping algorithm is proposed to overcome this problem. The candidate OFDM frames transmitted on antennas are decomposed to be real and imaginary part, thereby, a sufficiently large number of alternative transmit ...
