WEIGHT ROTATION TECHNIQUE FOR PAPR REDUCTION IN OFDM
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 5
Abstract
In this paper we propose Weight Rotation Technique for peak to- average power ratio (PAPR) reduction in OFDM systems. It is based on selected mapping (SLM) algorithm. The main drawback of the conventional SLM technique is their high signal processing complexities due to the use of multiple inverse fast Fourier transform (IFFT) operations per OFDM block. In the proposed PAPR reduction is based on a preset threshold value and the phase sequence is modified accordingly. Simulation results show that this technique gives a performance close to SLM technique with considerable reduction in complexity
