针对在无线电监测和认知无线电系统中,信号参数估计这一重要问题,证明了OFDM信号具有循环平稳性的必要条件是加循环前缀或有非矩形脉冲成型,并以线性周期时变变换(LPTV)模型为基础,推导了OFDM信号的循环谱表达式-For radio monitoring and cognitive radio systems, signal parameter estimation of this important issue, the necessary condition for the OFDM sig

针对认知无线电系统中正交频分复用( OFDM )信号参数估计这一重要问题, 利用OFDM 信号的循环谱实现了符号周期的盲估计。-For cognitive radio systems, orthogonal frequency division multiplexing (OFDM) signal parameter estimation of this important issue, the cyclic spectrum of the OFDM signal to achieve the

本文有关于OFDM循环谱的推导 可贵的是还有带循环前缀的循环谱推导 仿真了OFDM循环谱，介绍了相关理论估计盲信号参数以及改进算法-The OFDM cyclic spectrum and bilnd signal estimating

分析了该信号的时域、频域、倒谱，循环谱等,包括广义互相关函数GCC时延估计，这个有中文注释，看得明白。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Including the generalized cross-correlation function GCC time delay estimation, The Chinese have a comment, und
