摘要: A peak-to-average power ratio (PAPR) reduction method, known as system-aided PAPR reduction (SAPR), is disclosed. Based on a TR algorithm, the SAPR method avoids the drawbacks of conventional tone reservation implementations, and reduces PAPR significantly, in some embodiments. The SAPR method may be applied to next generation OFDMA-based wireless broadband technologies, to increase system throughput and cell coverage.

摘要: A weighted tone reservation (WTR) method and system are disclosed, for PAPR reduction. The WTR method solves the peak re-growth problem with minimum overhead. By avoiding the drawbacks of conventional tone reservation approaches, systems employing the WTR method may experience a significant PAPR reduction. The WTR method may be applied to next generation OFDMA-based wireless broadband technologies to increase system throughput and cell coverage.
