Nonparametric VSS-APA based on precise background noise power estimateWEN Hao-xiang(文昊翔)1, LAI Xiao-han(赖晓翰)2, CHEN Long-dao(陈隆道)2, CAI Zhong-fa(蔡忠法)2(1. College of Physics and Mechanical &... problematic term of its variable step-size formula is the value of background noise power (BNP). The power difference between the desired signal and output signal, which equals the power of error......
-Verlag Berlin Heidelberg 2012 Abstract: A new approach for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems was proposed. This approach is based on assigning powers to the different subcarriers of OFDM using an unequal power distribution strategy. In addition, a reduced complexity selective mapping (RC-SLM) scheme was proposed. The proposed......
