Peak-to-average Ratio Reduction Scheme For Multi-carrier Systems With Block-based Channel Estimation

摘要

A simple scheme is proposed to rcduce the peak-to-average ratio (PAPR) for multi-carrier systems with block-based channel estimation, where each user simultaneously transmits multiple traffic blocks across the frequency, and the channel estimation is done within each block. Unlike most existing schemes, the proposed scheme docs not require additional side information or estimation at the receiver. Results indicate significant improvements in both the PAPR and cubic metric reduction.
