<p>Disclosed are a digital signal processing apparatus and a wireless communication system for controlling cell boundary interference using an active antenna system, and a method for controlling cell boundary interference. The system comprises: a digital signal processing apparatus for processing a wireless digital signal, the digital signal processing apparatus being connected to a core system; and a plurality of active antenna systems including an active antenna capable of antenna tilting and beamforming for vertical cell division, the active antenna being physically separated from the digital signal processing apparatus, and a wireless signal processing apparatus for converting and amplifying the digital signal received from the digital signal processing apparatus, transmitting the signal to a terminal through the active antenna, receiving the signal transmitted from the terminal through the active antenna and transmitting the received signal to the digital signal processing apparatus. In the case where interference increases on cell boundaries formed by the active antenna, the digital signal processing apparatus controls the interference on the cell boundaries by forming additional cells on the cell boundaries and dividing the existing cells into a greater number of cells.</p> |
