| Abstract: | Based on the cyclic cumulant of ZPOFDM signals,a blind parameter estimation algorithm is proposed to estimate parameters such as symbol period,zero-padding time guard interval,and subcarrier number under the environment of fading channel.According to the explicit derivation and analysis of expression for the second order cyclic cumulant of ZPOFDM signals,the spectral lines features of the profile are investigated,and the algorithm steps are given simultaneously.The estimated performance is analyzed.The expe... |
