Weighted tone reservation for OFDM PAPR reduction
Abstract:
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.
