Peak-to-Average-Power-Ratio (PAPR) reduction in WiMAX and OFDM/A systems
A peak to average power ratio (PAPR) reduction method is proposed that exploits the precoding or beamforming mode in WiMAX. The method is applicable to any OFDM/A systems that implements beamforming using dedicated pilots which use the same beamforming antenna weights for both pilots and data. Beamforming performance depends on the relative phase shift between antennas, but is unaffected by a p...

متن کاملPeak to Average Power Ratio (papr) Reduction Techniques for Ofdm-mimo System
In the previous chapter, to get high data rate transmission, High Throughput techniques were analyzed for OFDM-MIMO System. OFDMMIMO systems based on OFDM symbols suffer from the problem of inherent Peak to Average Power Ratio (PAPR). The peak power of a multi carrier OFDM signal is a critical design factor for band limited communication systems, and it is necessary to reduce it as much as poss...
متن کاملPeak-to-Average Power Ratio Reduction Techniques for OFDM Signals
Orthogonal frequency division multiplexing (OFDM) has been adopted as a standard for many modern wireless applications requiring high data rate due to bandwidth efficiency, resistance to frequency selective fading and simple digital realization using IFFT/FFT operations. However, physical implementation of the OFDM system suffers from several difficulties. One of the major limitations of OFDM i...
