Bidirectional Neural Radio-Frequency Radiance Fields for 6-D Channel Knowledge Map Construction
This letter studies the construction of six-dimensional (6D) any-to-any (X2X) channel state information (CSI) maps, a specific type of channel knowledge map (CKM), for single-input multiple-output (SIMO) systems with varying transmitter (Tx) and receiver (Rx) locations, using limited measurements. We propose a novel bi...
