Performance Comparison of Two Clipping Based Filtering Methods for PAPR Reduction in OFDM Signal
The growth of wireless communication technologies has been producing the intense demand for high-speed, efficient, reliable voice & data communication. As a result, third generation partnership project (3GPP) has implemented next generation wireless communication technology long term evolution (LTE) which is designed to increase the capacity and speed of existing mobile telephone & data network...
متن کاملPAPR Reduction in OFDM using Clipping and Filtering
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is an emerging field of research in the field of wireless communication and finds its application where high data rate is required at low latency and better spectral efficiency. Peak to Average Power Ratio (PAPR) is the limiting factor for an OFDM system as it degrades the system performance by reducing SQNR of ADC/DAC as well as affec...
متن کاملReduction of Papr in Ofdm by Clipping
One of the main disadvantages of Orthogonal frequency division multiplex (OFDM) is high peak-to-average power ratio (PAPR). The clipping method of PAPR reduction is analyzed in this article.
متن کاملPerformance Evaluation for OFDM PAPR Reduction Methods
The ultimate goal of Peak to Average Power Ratio (PAPR) reduction for Orthogonal Frequency Division Multiplexing (OFDM) signals is to reduce the signal’s sensitivity to nonlinearity and to improve signal quality and transmitter power efficiency. Performance evaluation has traditionally been based mainly on the PAPR distribution curves. For clipping related methods, however, tradeoffs between PA...
متن کاملPerformance Improvement of OFDM System Using Iterative Signal Clipping With Various Window Techniques for PAPR Reduction
OFDM signals demonstrates high fluctuations termed as Peak to Average Power Ratio (PAPR).The problem of OFDM is the frequent occurrence of high Peaks in the time domain signal which in turn reduces the efficiency of transmit high power amplifier.In this paper we discussed clipping and filtering technique which is easy to implement and reduces the amount of PAPR by clipping the peak of the maxim...
