Embodiment Construction

[0081] The invention provides a combined transmission method and device for cell signals, which are used to solve the technical problem that the converging equipment has relatively large noise when combining signals.

[0082] In order to solve the problems of the technologies described above, the general thinking of the present invention is as follows:

[0083] A method for combined transmission of cell signals, the method comprising:

[0084] The converging device receives N cell signals from the remote device, where N is a positive integer greater than or equal to 2;

[0085] The convergence device separates each of the N cell signals into K sub-signals, and obtains N multiplied by K sub-signals, where K is a positive integer greater than or equal to 2;

[0086] The converging device performs noise component elimination processing on the K sub-signals of the signal of each cell, and obtains N times K processed sub-signals;

[0087] The converging device combines the N time...

Abstract

The invention discloses a cell signal combination transmission method and device. The method comprises the following steps that converging equipment receives N cell signals from remote equipment, wherein N is a positive integer larger than or equal to 2; the converging equipment separates each cell signal in the N cell signals into K sub-signals, thereby obtaining NXK sub-signals, wherein K is a positive integer larger than or equal to 2; the converging equipment is used for eliminating noise components on the K sub-signals of each cell signal to obtain NXK processed sub-signals; and the converging equipment is used for combining the NXK processed sub-signals to obtain a combined signal, and transmitting the combined signal to a baseband processing unit, so that signal transmission is finished.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a combined transmission method and device for cell signals. Background technique [0002] For public network systems, indoor coverage is a very important part. At present, various operators are actively deploying various indoor remote units or similar antenna equipment, so that wireless devices can provide sufficient coverage indoors. [0003] Please refer to figure 1 or figure 2 As shown, it is a schematic diagram of two commonly used indoor distribution systems. in, figure 1 As a traditional indoor distribution system, the uplink signals of each small antenna are connected to the radio remote unit (Radio Remote Unit, RRU) through a power divider, and then the analog remote convergence device (rHub) adopts simple signal equal power combination or adopts Power divider combining method, multiple signals are combined, and connected to the baseband proces...
