Multi-mode base station upstream reception system and method thereof

Abstract

The invention relates to a multi-mode base station upstream reception system and a method thereof. The system comprises an AGC (Automatic Gain Control) module, a communication standard controlling module and a data processing module, wherein the communication standard controlling module controls the AGC module to carry out amplitude adjustment on a data signal from a base station antenna and controls the data processing module to carry out modulation and demodulation treatments on a CDMA communication standard signal or an LTE communication standard signal. Through the communication standard controlling module, the data processing module is controlled to carry out selection switching of the data signal, real-time baseband signal upstream reception demodulation processing of an arbitrary standard in WCDMA, TD-SCDMA and LTE communication standards is realized, and compatibility is good. Besides, a plurality of same function modules of the three communication standards can be reused, and resource consumption is reduced. Comprehensive property of the system is improved. Through adding relevant modules, baseband signal processing of an arbitrary standard is realized, and scalability is good. A plurality of standards employ a same chip, platform configurations of different products can be unified, a same single board is used, and cost of research & development, purchase and maintenance are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-mode base station uplink receiving system and method in the uplink receiving part of a mobile communication system. Background technique [0002] According to the evolution and development of existing networks, the future direction of wireless network development will be a wireless network that supports multi-mode access. In such a network, a variety of different access technologies must be seamlessly integrated in a single wireless access network, and end users do not need to know which way they need to access the network at present. [0003] The future mobile communication access network will also be a multi-communication standard communication network in which multiple communication standards coexist (aliasing), and will use a variety of air interface technologies with different coverage and capacity, such as WCDMA (Wideband Code Division Multipl...

Problems solved by technology

[0009] For the above method 1: the system operator needs to prepare different boards for different communication systems, which increases the cost of the system operator; in addition, when switching between different communication systems, it is necessary to manually go to the base station for on-site maintenance, and the maintenance cost is relatively high

Moreover, equipment manufacturers also need to produce different boards for different communication standards, and at the same time need to develop different systems for different boards, which increases R&D and processing costs

[0010] For the above method 2: the system operator also needs to prepare different single boards with different chips soldered for different communication standards, which increases the cost of the system operator

In addition, when switching between different communication systems, it is also necessary to manually go to the base station for on-site maintenance, which increases maintenance costs; equipment manufacturers need to solder different chips for different communication systems, which increases processing costs
