PAPR Reduction of OFDM Signals Using Selective Mapping and Clipping Hybrid Scheme

Free registration required

Executive Summary

The orthogonal frequency division multiplexing is one of the modulation techniques widely used in the broadband wireless technology. One of the main problems of this technology is the high peak-to-average power ratio of transmission signal due to the superposition of many subcarriers. This paper presents a new hybrid peak-to-average power ratio reduction technique, which combines a selective mapping method with the clipping method. The paper presents the performance and advantages of the new technique and compares it with other existing methods.
