| Abstract: | The SNR of the received signal can be increased in long range underwater communication with beamforming technology. A constant width beamforming simulator SWARRY was proposed in order to evaluate the performance of beamforming technology to underwater communication systems. Based on improved adaptive beam synthesis method and time domain beamforming technology, the simulator could simulate array output at different conditions. Combined with a direct sequence spread spectrum system, its validity in underwater communication simulation was proved. |
