FDD Massive MIMO Channel Estimation with Arbitrary 2D-Array Geometry
This paper addresses the problem of downlink channel estimation in frequency-division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems. The existing methods usually exploit hidden sparsity under a discrete Fourier transform (DFT) basis to estimate the cdownlink channel. However, there are at least two shortcomings of these DFT-based methods: 1) they are applicable to unifor...
متن کاملChannel Estimation for Fdd Massive Mimo Using Bayesian Estimator
Massive MIMO systems that for a cellular network, the channel from user equipment to a base station is composed of few grouped paths in space. With a very large antenna array, signals can be observed under extremely sharp regions in space. In the FDD mode, each BS sends a downlink training matrix to its served UEs which estimates the desired channel based on the downlink measurements and feeds ...
متن کاملChannel Estimation for TDD/FDD Massive MIMO Systems with Channel Covariance Computing
In this paper, we propose a new channel estimation scheme for TDD/FDD massive MIMO systems by reconstructing uplink/downlink channel covariance matrices (CCMs) with the aid of array signal processing techniques. Specifically, the angle information and power angular spectrum (PAS) of each multi-path channel is extracted from the instantaneous uplink channel state information (CSI). Then, the upl...
متن کاملDictionary Learning Based Sparse Channel Representation and Estimation for FDD Massive MIMO Systems
Downlink beamforming in FDD Massive MIMO systems is challenging due to the large training and feedback overhead, which is proportional to the number of antennas deployed at the base station, incurred by traditional downlink channel estimation techniques. Leveraging the compressive sensing framework, compressed channel estimation algorithm has been applied to obtain accurate channel estimation w...
متن کاملSemi-Blind Channel Estimation based on subspace modeling for Multi-user Massive MIMO system
Channel estimation is an essential task to fully exploit the advantages of the massive MIMO systems. In this paper, we propose a semi-blind downlink channel estimation method for massive MIMO system. We suggest a new modeling for the channel matrix subspace. Based on the low-rankness property, we have prposed an algorithm to estimate the channel matrix subspace. In the next step, using o...
