Abstract For solving the main conflict between the direction of arrival for the radio signal and maintaining the signal details in the wireless communication, this paper presents a novel algorithm for improving the radio signal processing. In order to receive the strongest radio wave from the antenna array, the direction estimation for wireless communication is approached under radio electromagnetic spectrum broadband, in which there are the multiple transmitting antennas and the multiple receiving antennas. We construct the focusing matrix for each frequency point, and then we use the uniform linear array to establish a mathematical model to simulate the direction of arrival for the smart antennas.
