Performance Evaluation of OPS-SAP PAPR Reduction Technique in OFDM Systems in a Wireless Vehicular Context

Vehicular Ad Hoc Networks (VANETs) are wireless networks that emerged thanks to advances in wireless technologies and in the automotive industry. Orthogonal Division Multiplexing (OFDM) has been adopted as a candidate for IEEE 802.11p standard due to its advantages. However, one of the most serious issues is the high Peak-to-Average Power Ratio (PAPR) of the transmitted signal. When the signal with high peaks passes through a nonlinear High Power Amplifier (HPA), the peaks generate distortions in the signal, which degrades the performance. In this paper, we propose the application in these VANETs scenarios of OPS-SAP, a PAPR reduction technique, and its evaluation for an IEEE 802.11p standard.
