Weighted Inter-frame Averaging-Based Channel Estimation for CO-OFDM System
IEEE Photonics Journal, 2013 We propose an efficient channel estimation method for coherent optical orthogonal frequency-division multiplexing (CO-OFDM) based on weighted inter-frame averaging (WIFA), in which the channel estimation results of the adjacent frames are averaged to ...

2-D DOA tracking using variational sparse Bayesian learning embedded with Kalman filter
EURASIP Journal on Advances in Signal Processing, 2018 In this paper, we consider the 2-D direction-of-arrival (DOA) tracking problem. The signals are captured by a uniform spherical array and therefore can be analyzed in the spherical harmonics domain.
