Abstract: A signaling-type method for mobile phone signals, comprising: establishing a shielding processing system, and ensuring that the frequency reference of said system is synchronized with that of a base station; using the feature that a frame signal of a base station is repeatedly transmitted according to a frame period of the base station, receiving the frame signal of the base station at different times; performing filtering processing on the frame signals of the base station using a frame averaging method, so as to obtain purified frame reference signals of the base station; and using the purified frame reference signals to shield the base station.

Abstract: The disclosure discloses a method for distributing pilot frequency in a massive antenna system, including: dividing a pilot frequency set into three sub sets that are intersecting with each other, and then dividing the users of each cell into a cell central user and a cell edge user. The cell central users use an intersection set of three pilot frequency sub sets. The cell edge users of all cells use a difference set, an intersection set and a union set of three pilot frequency sub sets according to a certain rule. When it is designing to implement the pilot resource distribution plan of the massive antenna system, three cells that are adjacent with each other in the system are used as a cluster, and a pilot frequency use plan of any one cluster may be designed according to the method proposed by the disclosure, and then the same design plan is applied to other clusters in the system, and then is adjusted according to the user distribution of each cluster and the business distribution circumstance thereof.

Abstract: The present invention provides a digital optical fiber-based distributed signal control system. The system mainly comprises a wireless signal access control module, a detection module, and a private network module. By means of reasonable frequency allocation and pre-selection filtering processing, modules can work together to implement control and detection of unauthorized mobile phone signals and guarantee communications of legal mobile phones, thereby achieving efficient coverage of a signal control area. A main control signal generated by a main control signal unit (SU) and an auxiliary control signal generated by a remote unit (RU) are mixed according to an algorithm, to achieve a better control effect in the entire signal control area.
