time-of-arrival correlationstime-of-arrival correlationsWe propose that measurements of time-of-arrival correlations in multipartite systems can sharply distinguish between different approaches to the time-of-arrival problem. To showthis, we construct a positive-operator-valued measure for two distinct...
In this paper, a novel time-of-arrival estimation algorithm is proposed for impulse radio-based UWB systems in dense multipath environment. In particular, a dedicated ranging sequence with good cross-correlation property is proposed and a threshold-based search-back unit is introduced, with the pur...
We consider a time-of-arrival (ToA) estimation in the presence of path attenuation. Maximum correlation (MC) is revisited and maximum likelihood (ML) is newly derived to estimate the ToA. It reveals that for low effective bandwidth, short distance and large path loss exponent, the ML has a...

The acquisition probability of two popular algorithms are investigated,which are based on general cross correlation(GCC) algorithm and widely used to evaluatetime difference of arrival(TDOA) coefficients. 对基于广义互相关法(GCC)的波束到达时间差(TDOA)估计算法的捕获概率进行了分析,推导了计算捕获概率的数值...
The advantage of this receiver scheme is relatively easy implementation when compared with the correlation based scheme. The drawback of the non-coherent approach is the noise enhancement due to the squaring and the degradation in time resolution that is proportional to the length of the integration...
Such a proposed method only uses the time-domain cross-correlations between the received signal and the transmitted NPRS, and has a low complexity. We show through simulations that, the ToA estimation of the proposed method performs close to the maximum likelihood (ML) estimation for a single-...
