A new root-based direction-finding algorithm
[1] Polynomial rooting direction-finding (DF) algorithms are a computationally efficient alternative to search-based DF algorithms and are particularly suitable for uniform linear arrays of physically identical elements provided that mutual interaction among the array elements can be either neglected or compensated for. A popular algorithm in such situations is Root Multiple Signal Classificati...
متن کاملA new Unitary ESPRIT-based technique for direction finding
A new pseudo-noise resampling technique is proposed to mitigate the effect of outliers in Unitary ESPRIT. This scheme improves the performance of Unitary ESPRIT in unreliable situations, where the so-called reliability test has a failure. For this purpose, we exploit a pseudo-noise resampling of a failed Unitary ESPRIT estimator with a censored selection of “successful” resamplings recovering t...
متن کاملAn Improved Direction Finding Algorithm Based on Toeplitz Approximation
In this paper, a novel direction of arrival (DOA) estimation algorithm called the Toeplitz fourth order cumulants multiple signal classification method (TFOC-MUSIC) algorithm is proposed through combining a fast MUSIC-like algorithm termed the modified fourth order cumulants MUSIC (MFOC-MUSIC) algorithm and Toeplitz approximation. In the proposed algorithm, the redundant information in the cumu...
متن کاملNew Methodology to Approximate Type-Reduction Based on a Continuous Root-Finding Karnik Mendel Algorithm
Interval Type-2 fuzzy systems allow the possibility of considering uncertainty in models based on fuzzy systems, and enable an increase of robustness in solutions to applications, but also increase the complexity of the fuzzy system design. Several attempts have been previously proposed to reduce the computational cost of the type-reduction stage, as this process requires a lot of computing tim...
متن کاملDirection Finding Algorithm with Virtual Antenna Array
Background: Direction finding (DF) based on MUSIC algorithm has been studied and implemented in the wireless communications lab. Simulation results, measurement setup are shown in the figures below. Most of the direction finding (DF) algorithms require multiple antennas with at least í µí¼/2 spacing. Also, performance of the DF algorithms mainly relies on Number of antennas in the antenna ar...
