Abstract
The invention relates to a home base station system on the basis of the software radio. In the system, after a signal is digitalized, data is directly accessed into a PC (Personal Computer) through a fixed port; all digital processing parts are completed by PC software; and the newest frameware packets can be downloaded in real time for the software through the Internet, so that the multi-system and multifunctional upgrading is realized. The design of the home base station on the basis of the software radio is characterized in that all the modulation and demodulation processes are completed through the PC software, so that the hardware cost of the base station is greatly reduced, a receiving front end is also simpler. In system software, all communication modules and processing modules are made into plugins of the system software; the plugins are all written on the basis of C plus plus; an algorithm is flexible and is easy to update; various voice processing functions can be added; the complete processing process is full digitalized; and the home base station can easily correct an error and maintain an AD (Analog to Digital) acquisition system in the home base station.
Description
Technical field
The present invention relates to a kind of Home eNodeB end, specially refer to software programming and realize communication process based on software radio.
Background technology
It is characterized in that in a kind of family base station system: directly data are inserted PC after signal digitalized through fixed port based on software radio; All digital processing parts are all accomplished through PC software; Software can be downloaded the latest firmware bag in real time through INTERNET; Realize multi-modulation scheme, multi-functional upgrading.The design of the Home eNodeB of software radio is characterized in that all modulation, demodulating process all through the completion of PC software, make the hardware cost of base station significantly reduce, and it is more simple that receiving front-end also becomes.
Software radio is a technology that lets the as close as possible reception antenna of soft code.It can be dealt with problems wireless logical circuit to be put in the software and solve.The most basic characteristic of software radio is the waveform through the transmission of software modulation radio, the waveform that software demodulation receives.This has distinct difference with at present most by the mould electricity or by the radio that the modulus combinational circuit is formed.Software radio is huge revolution, makes that to set up RF more flexible, to the user bring more maybe.Software radio can be good at realizing that conventional wireless electricity can realize and irrealizable function; In addition; The maximum shock of software radio is the flexibility that software offers us; For many years, we can see traditional wireless device of forming by a lot of immobilising devices will by, the communication equipment that general device is formed replaces.So it is development in future trend that Home eNodeB adopts software radio.
Summary of the invention
Technical problem of the present invention is that a kind of family base station system based on software radio will be provided, and it is characterized in that: hardware components finally is output as the AD digital signal, has saved the digital processing chips such as CPU of Home eNodeB in the past; This segment chip price is high, and volume is big, the upgrading difficulty; If the communication of new standard is arranged, must upgrade to whole hardware components, have a big risk like this; Cost is high, poor practicability.And, can solve this part difficult problem based on the digital processing platform of software radio.In systems soft ware, all communication modules, processing module is made into the plug-in unit of systems soft ware, and plug-in unit is all write as based on C++, and algorithm flexibly and be easy to upgrading and can add multiple language process function, and the total digitalization of entire process process is easy to error correction, safeguards.
