A novel method for two-dimensional direction-of-arrival estimation of coherently distributed (CD) noncircular sources is proposed. It is the first time that we introduce the noncircularity of signal into CD model to estimate central azimuth angle and central elevation angle. Numerical simulations are also provided in contrast with the other ESPRIT-like(More)
In this communication, a novel low-complexity method for two dimensional (2D) DOA estimation of coherently distributed noncircular sources impinging on L-shape sensor array is proposed. Firstly, according to the noncircular property, the proposed method utilizes both the received signals and its conjugate to extend the received data matrix and form extended(More)
The location method based on TOA estimation is a research hotspot in the field of wireless location. In this paper, an new TOA estimation algorithm is proposed for providing a better estimation performance. The cross correlation matrix is employed to process channel estimation in frequency domain, which is benefit to the noise suppression. Channel(More)
In this paper, a new estimator of coherently distributed source employing the sparse representation technology is proposed by utilizing subspace fitting principle. The proposed method uses the eigenvalue-decomposition method on the sample covariance matrix of the sensor array received data and obtains the signal eigenvectors. We represent the generalized(More)
a novel distributed frequency allocation scheme named as exponential distribution based frequency allocation (EDFA) is proposed in Fractional Frequency Reuse (FFR) aided OFDMA networks. EDFA has a flexible adjustment between fairness and throughput. Simulation results demonstrate that compared to the proportional fairness (PF) allocation and equal rate(More)
BACKGROUND Monotherapy and sequential combination therapy have been widely used in the treatment of pulmonary arterial hypertension (PAH). There is limited evidence for initial combination therapy in patients with PAH, particularly those with World Health Organization (WHO) functional class III or IV. METHODS Twenty-seven consecutive treatment-naive PAH(More)
In this communication, a new method is proposed to estimate the central direction-of-arrival (DOA) of multiple incoherently distributed noncircular sources from using the received data in two closely spaced uniform linear arrays. Both the received data vector and its conjugate are utilized to estimate the extended crosscorrelation (CC) matrix. Singular(More)
In practical array signal processing applications, the performance of DOA (direction-of-arrival) estimation methods is known to degrade severely in the presence of angular spread. In this paper, a new approach of estimating parameter via block sparse Bayesian learning is proposed for multiple incoherently distributed sources. Unlike traditional subspace(More)
