ESPGD Algorithm to Improve the Convergence Speed for Adaptive Single-Mode Fiber Coupling

The adaptive single-mode fiber (SMF) coupling technique is normally adopted since the coupling efficiency (CE) significantly determines the performance of the free-space optical communication (FSOC) systems. The stochastic parallel gradient descent (SPGD) algorithm is the most commonly used control...
