Theory of AdaDelSPGD Algorithm in Fiber Laser-Phased Array Multiplex Communication Systems

Stochastic parallel gradient descent (SPGD) algorithm is one of the most promising methods for effective coherent beam combination. However, the algorithm also has some disadvantages, such as slow convergence speed and local extremum. This paper proposes an AdaDelSPGD algorithm, which combines an Ad...
