Description
Technical field
The present invention relates to wireless communication technology field, GGE systems receive data processing side under more particularly to a kind of multi-user
Method and processing unit.
Background technology
Communication system is the general name of the technological system for completing message transmitting procedure.Modern Communication System is main by electricity
Magnetic wave realizes that the former is referred to as wireless communication system, the latter in the propagation of free space or the transporting mechanism in guide media
Referred to as wired communication system.Include a class GGE systems in a wireless communication system, the GGE systems are gsm system, gprs system
And the set of EDGE systems, i.e., gsm system, gprs system and EDGE systems are supported simultaneously.
Wherein, gsm system is entirely entitled：Global System for Mobile Communications, Chinese is the whole world
Mobile communcations system, is commonly called as " Global Link ", is a kind of mobile communication technology standard for originating from Europe, is Generation Mobile Telecommunication System
Technology, its exploitation purpose is to allow all parts of the world can be used in conjunction with a mobile telephone network standard, allows user to use a hand
Machine can just manage it all over the whole world.Gsm system uses GMSK modulation mode transceiving data.Gprs system is entirely entitled：General Packet
Radio Service, Chinese is general packet radio service technology, and it is a kind of available mobile number of gsm mobile telephone user
According to business.Gprs system can say be gsm system continuity, GPRS is different in the mode of channel transmission with the past continuous, is with envelope
Bag（Packet）Mode is transmitted, therefore the expense that user is born is calculated with its data transmission unit, and non-usage its
Whole channel, in theory inexpensively.Gprs system uses GMSK modulation mode transceiving data.EDGE systems are entirely entitled：
Enhanced Data Rate for GSM Evolution, Chinese is enhanced data rates for gsm evolution technology.EDGE systems
It is a kind of from gsm system to the transitional technology of 3G systems.EDGE systems are received using GMSK modulation mode or 8PSK modulation mode
Hair data.
Subsequently, GGE system dockings receive data processing method under introducing existing multi-user, specifically, refer to
Fig. 1, it is the schematic flow sheet of GGE systems reception data processing method under existing multi-user.As shown in figure 1, existing
Under multi-user in GGE systems reception data processing method, when channel configuration is gsm system type or gprs system type,
The data that acquiescence is received are GMSK modulation, perform GMSK equilibrium flows；When channel configuration is EDGE system types, it is modulated
The blind Detecting of mode, that is, judge that modulation system is that GMSK modulation or 8PSK are modulated, if testing result is GMSK modulation, equally holds
Row GMSK equilibrium flows, otherwise perform 8PSK equilibrium flows.
Such implementation process, mistake is will appear from when in face of following situation：
In the case of multi-user, the channel configuration of this user A is gprs system type, the user in the same time slot of distribution
B is configured to EDGE system types.When network sends the data of 8PSK modulation mode to user B, this user A also connects in this time slot
Have received data（I.e. network is sent to the data of the 8PSK modulation mode of user B）.According to existing balance policy, this user A
To go to decode the data of this 8PSK modulation mode according to GMSK equalization methods, at the same the certain soft bit of output and, when partially and frequency
Decoded information is waited partially.If output soft bit and more than desired threshold value, then it is assumed that output when partially etc. information be it is reliable,
The data that follow-up this user A is received will will so cause follow-up timing all to make a mistake according to timing adjustment is now done partially.
