Estimating the Number of Wideband Radio Sources

In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...

TDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire

Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...

Estimating the number of sources using independent component analysis

1. Introduction Estimating the number of sources provides useful information for signal processing applications, such as blind source separation (BSS) in the frequency domain [1]. It is well known that the number of dominant eigenvalues of the spatial correlation matrix corresponds to the number of sources [2,3]. However, it is difficult to distinguish dominant eigenvalues from the other eigenv...

Passive Localization of Mixed Far-Field and Near-Field Sources without Estimating the Number of Sources

This paper presents a novel algorithm for the localization of mixed far-field sources (FFSs) and near-field sources (NFSs) without estimating the source number. Firstly, the algorithm decouples the direction-of-arrival (DOA) estimation from the range estimation by exploiting fourth-order spatial-temporal cumulants of the observed data. Based on the joint diagonalization structure of multiple sp...
