Mixing Matrix Estimation in Blind Source Separation Based on CFSFDP
2019 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2019 Mixing matrix estimation is one of the key techniques in underdetermined blind source separation. To obtain an accurate estimation of mixing matrix, an effective estimation algorithm based on clustering by fast search and find of density peaks (CFSFDP) is proposed in this paper.

Mixing Matrix Estimation Method for UBSS based on Observed Data Segmentation
Proceedings of the 8th International Conference on Communication and Network Security, 2018 This paper presents a mixing matrix estimation method for underdetermined blind source separation (UBSS) when source signals are insufficiently sparse. Main ideas are as follows: Observed signals are segmented. Then mixing matrices for every segment of observed signals are estimated using overdetermined blind source separation (OBSS) algorithms, and ...

On the Information Matrix in Mixed Logit Models Estimation
Transportation Research Record: Journal of the Transportation Research Board, 2011Advanced discrete choice models—in particular, mixed logit models—are used extensively in transportation. Although much progress in estimation techniques has made them numerically appealing, their properties have not been fully explored. This lack of exploration sometimes leads to confusing quality measurements and misinterpretation of the estimates ...

Mixing matrix estimation algorithm based on single source detection
2016 IEEE 13th International Conference on Signal Processing (ICSP), 2016In this paper, the input signal's short time Fourier transformation and the sparsity condition satisfied in the time-frequency domain are given firstly. Then, the feasibility of the single source detection using the wideband radar signal based on the eigen-value decomposition is analyzed theoretically.

Efficient Estimation of Mixing Matrix Using a Two-sensor Array
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020Blind source separation involves the estimation of mixing matrix given only observed mixtures. Considering the computational cost in practice, this paper proposes an efficient mixing matrix estimation (MME) method using an easily configured two-sensor array. Time-frequency (TF) analysis, which has been an important field of research for MME, is invoked
