Near-Field Sparse Channel Representation and Estimation in 6G Wireless Communications

The employment of extremely large antenna arrays and high-frequency signaling makes future 6G wireless communications likely to operate in the near-field region. In this case, the spherical wave assumption which takes into account both the user angle and distance is more accurate than the convention...
