Near-Field Channel Estimation via Mixed Norm and Sub-Array Sparse Recovery

Abstract: The deployment of extremely large-scale multiple-input multiple-output (XL-MIMO) significantly enlarges the near-field region. Accurate near-field channel state information estimation is of ...

Fourth-Order Sparse Array Design From a Sum-Difference Co-Array Perspective

Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...
