Abstract

The present application belongs to the technical field of mobile communications. Provided are a MIMO communication system and control method for feeding in signals at two ends of a leaky cable. By means of the present application, 2*2 MIMO, 4*4 MIMO, even 8*8 MIMO, etc. can be implemented by feeding in different signals at two ends of a single leaky cable, such that space can be saved on, system costs can be reduced, and the user-perceived rate of a network is also increased. Moreover, by means of additionally providing signal controllers and positioning base stations and by using a corresponding signal strength adjustment control method, the problem of reception differences between mobile terminals being great and same being hard to handle due to signal unevenness of two signals can be solved. On the basis of the location of a terminal, the system can control, in real time, changes in the strengths of signals which are input into a leaky cable, such that the strengths of two signals received by the terminal is controlled to be within a device processing range, thereby ensuring the communication quality.
