Joint estimation of DOA and channel errors with sparse recovery for SKA low-frequency array

Joint estimation of DOA and channel errors with sparse recovery for SKA low-frequency array

Here, the authors present an improved and fast sparse recovery method for joint estimation of channel errors and direction of arrival (DOA) for square kilometre antennas low-frequency array. Since this array is formed of a large number of antennas and distributed in a very large space, array calibra...
