This paper discusses the collaborative beamforming problem using improved directional perturbation approach based on one bit feedback scheme. There are multiple transmitters and receiver in our setup, all send a common signal synchronously, return of to transmitters. Each transmitter uses only local information adjust its phase every time slot. An algorithm is proposed improve convergence accuracy. The properties alignment investigated by simulation, simulation results verify that accuracy outperforms original algorithm. Moreover, simulations also show has advantages scalability.
