Research on the New Algorithm using Multi-Array Computation Signal Direction
With the rapid development of the social economy, the mobile communication industry has faced new development opportunity and been fully into our life. However, with the development of all communication technologies and the increasing of the mobile communication user, the traditional communication technology is strongly dependent on the frequency. However, the frequency resource has restricted the development of the communication industry.3G communication technology has solved the problem of the frequency limitation. SDMA (Space Division Multiple Address) is one of the critical technologies in the 3G communication, which can reuse the frequency by marking the same frequency of the antenna beam in the different directions. 3G communication has been into our life deeply, requiring the corollary equipment to keep up with the pace and adapt to the more rapid and intellectual development. As the signal transmitting and receiving equipment in the mobile communication system, antenna is very critical for the whole system. The developments of 3G and 4G promote the development of the intellectual antenna. The traditional antenna cannot meet the requirements of the current mobile technology. The application of the intellectual antenna is through a series of the intellectual algorithms. A good algorithm is the sign of the intellectual antenna performance. The paper deals with the signals by researching the multi-array and finds out the signal direction rapidly and accurately, verifying the new algorithm by utilizing the simulating calculation.
