Frequency-domain-interleaving subspace algorithm for TDOA estimation of DS signal
Xiaotian Ren · Radio and communications technology · 2006
Two problems emerging when the frequency-domain super-resolution algorithms is utilized in TOA/TDOA of communication signals.Firstly,samples of the noises are characterized by non-white and non-stationary,and secondly,the total number of samples is not so many as to make full use of information contained in received signal.A frequency-domain interleaving method is proposed in this paper to solve above problems,together with the feasibility of the algorithm.The last part of this paper presents simulation results.
