In this paper, we consider the problem of direction-of-arrival (DOA) estimation in the presence of multi-path propagation. The sensor elements are assumed to be linear and uniformly spaced. To solve this problem, we propose a two step approach to perform DOA estimation in the presence of coherent signals for a uniformly spaced linear array of sensors. First, the effective steering vectors are estimated...
This paper proposes an improved natural gradient algorithm for blind source separation (BSS) based on the constrained optimization method. The improved algorithm introduces a scaling factor that restricts the training process by the balance spot, which adds little computational complexity and overcomes the conflict between the convergence rate and the steady-state accuracy. Therefore, the new algorithm...
To investigate the blind symbol rate estimation of any linear base-band digital modulation scheme with square root raised cosine filter, an algorithm based on cyclic correlation and Haar wavelet transform estimator is proposed. First we use FFT to estimate the bandwidth roughly. Then we set the sampling frequency and range scale of wavelet transform according to bandwidth. Using the signals filtered...
