Study on algorithms of microphone array for mobile phone

Microphone array has been widely applied to the conference mode, while the application on the mobile phone is still in the initial stage. Because hardware processing speed of mobile phone is low and the environment where we use mobile phone are complex as the restriction condition, now the use of microphone array technology on the mobile phone still has many difficulties needs to overcome. In order to reduce the cost of using microphone array on mobile phone, in this paper we only use two microphones forming a microphone array. We will explain some different algorithms and make experiments to compare with each other. Moreover, we get the most suitable algorithm under different environments.
