Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 It is a system structure diagram for realizing the access, transmission and signal coverage of CDMA signals in the embodiment of the present invention, and the specific description is as follows:

[0021] The whole system has a tree structure, and the business unit provides multiple branch interfaces downward for connecting the transmission unit or the user service interface unit. In order to realize more and more flexible user service interface unit access, the system supports multi-level expansion. At the same time, the service unit can directly connect to the user service interface unit without the transmission unit, or connect to the user service interface unit through the multi-level transmission unit. In this way, the system can realize flex...

Abstract

The invention discloses a method for realizing access and distribution of a CDMA signal and in a user station area, which comprises the following steps: converting a received CDMA radio frequency electrical signal into an optical signal and dividing into a plurality of paths of same optical signals for outputting; expanding and transmitting the received optical signals; converting the received optical signals into radio frequency signals and carrying out CDMA wireless signal distribution; in the uplink direction, converting the CDMA wireless signals received by a user into optical signals for outputting; combining a plurality of the received optical signals into one path for outputting; and respectively converting the plurality of the received optical signals into electrical signals for outputting, and then combining into one path and outputting. The method of the invention realizes the networking of the distribution system, can flexibly expand, changes the mode of utilizing a single power device to carry out CDMA wireless signal coverage, provides powerful support and guarantee for the indoor coverage construction of a CDMA mobile communication network, saves energy, is environment-friendly, and can reduce the repeated construction of wireless construction.

Description

technical field [0001] The invention relates to mobile communication wireless access network technology, in particular to a method for realizing access and distribution of CDMA signals in user resident areas. Background technique [0002] With the development of mobile communication network in China, at present, its users have exceeded 600 million, and the mobile phone ownership rate accounts for more than 45.7%. The entire mobile communication field contains a huge market space. For the more than 600 million mobile phone users who support the development and survival of operators, we can learn from the analysis of their behavior that indoor users are the value of the entire operator. Therefore, in order to attract more indoor users, improving their perception is the focus of operators. [0003] The CDMA network works in the 800MHz frequency band, including the 2G network of CDMA2000 1x and the 3G network of 1x EV-DO. [0004] At present, the construction method adopted fo...
