  • System aided PAPR reduction scheme based on TR algorithm
    Patent number: 8169959
    Abstract: 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.
    Type: Grant
    Filed: April 30, 2008
    Date of Patent: May 1, 2012
    Assignee: Intel Corporation
    Inventors: Rongzhen Yang, Hujun Yin, Xiaoliang Luo, Liang Jiang, Longjing Zhu
  • Weighted tone reservation for OFDM PAPR reduction
    Patent number: 7796498
    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.
