Coherently demodulated orbital angular momentum shift keying system using a CNN-based image identifier as demodulator

A two-dimensional (2D) direction-of-arrival (DOA) estimation method for coherently distributed sources has been proposed in highly real-time situation using only one snapshot. Ulizing two uniform linear arrays (ULAs), the proposed algorithm firstly construct four equivalent matrices with rotational structures using one snapshot, and then a total equivalent covariance is extended by the four matrices..Finally, two rotational invariance matrices can been calculate by ESPRIT-like algorithm, and
