Cramér-Rao Lower Bound for UWB Delay Estimation in Multipath Conditions
نویسنده
چکیده
The accuracy of wide band propagation delay estimation is characterized. The Cramér-Rao Lower Bound (CRLB) for delay estimation in multipath conditions is presented in terms of the Ricean K-factor, the ratio of direct to diffuse multipath components. The validity of the derivation is demonstrated using thousands of measurements, where the K-factor is estimated in the spectral domain.

متن کاملMaximum Likelihood Time Delay Estimation and Cramér-Rao Bounds for Multipath Exploitation
In this paper, time delay estimation using the maximum likelihood principle is addressed for the multipath exploitation problem, and the corresponding Cramér-Rao bounds are derived. A single wideband radar, and a target in a known reflecting geometry are assumed. If the multipath is indeed detectable and resolvable, it is shown here that multipath exploitation, firstly, permits estimating the a...
متن کاملCramer Rao Bound for Multipath Time Delays in a DS-CDMA System
In this paper a new modified Cramer-Rao lower bound (MCRLB) for multipath time-delay estimation is developed for DS-CDMA systems. The lower variance bound of each estimated path delay is determined via computer simulations using the theoretical results, and it is compared with an efficient and practical delay estimation method, namely peak tracking with pulse subtraction. Simulation results sho...
متن کاملCramér-Rao bound for range estimation
In this paper, we derive the Cramér-Rao bound (CRB) for range estimation, which does not only exploit the range information in the time delay, but also in the amplitude of the received signal. This new bound is lower than the conventional CRB that only makes use of the range information in the time delay. We investigate the new bound in an additive white Gaussian noise (AWGN) channel with atten...
متن کاملCramér-rao Lower Bound as a Performance Measure for High Resolution Multidimensional Channel Parameter Estimation Schemes
The Cramér-Rao lower bound (CRLB) is derived as a performance measure for multidimensional channel parameter estimation schemes. A compact formulation of the CRLB is given, revealing its dependence on the given wave parameters. Moreover, the SAGE algorithm is presented to yield a high resolution of the impinging electromagnetic field with respect to delay, azimuth and elevation. Furthermore, a ...
