Description
Technical field
The present invention relates to the communications field, in particular to a kind of reconstruction processing method and device.
Background technology
WCDMA（Wideband Code Division Multiple Access, referred to as WCDMA）It is
One of 3 g mobile communication air-interface standard.WCDMA belongs to spread spectrum communication, using Bidirectional closed-loop power control, transmitting and reception point
Collection, RAKE receive the technology such as anti-multipath fading, convolutional code and Turbo code channel coding/decoding.Mobile telecommunication channel and fixed communication
Channel is very different, and after the electromagnetic wave that when receiver is mobile, antenna receives can be launched by transmitter antenna, straight line reaches,
Can also reach after the mulitpath delay transit such as reflection, diffraction, therefore receipt signal has a lot of multipaths
（finger）Time delay, these multipath results interfere with each other, and form the multipath fading of wireless channel.In WCDMA Baseband Receiver generator terminal,
Using the dependency of Pilot PN code, multipath component distinguishable in receipt signal is tracked respectively, receives, output base band letter
Walking along the street footpath of number going forward side by side merges, and the mode of this receipt signal is referred to as RAKE and receives.RAKE receives and carries out correlation respectively to each multipath
Demodulation, the demodulator that these carry out correlation demodulation is also referred to as rake receiver（RAKE fingers）, then to these multipaths
The output of receptor merges, and feeding channel decoder carries out process below.RAKE receives and utilizes multipath component, equally
Increased the transmission power receiving, reach the purpose of anti-multipath fading.
In the WCDMA reception system of correlation technique, receive the multipath information obtaining and demodulating and decoding using RAKE
These multipath results in conjunction with channel estimation, are reconstructed, recover it and propagate in wireless channel by the user symbol after correct
Afterwards, amplitude during receiver end and phase information are reached.Then by these multipath alignment of data after reconstructing to original antenna number
According to timing added up, finally subtracted each other with original antenna data, thus balancing out user's multipath known to these
To unknown（Non- demodulating and decoding is correct）The impact of user, increases to remaining unknown subscriber's demodulating and decoding correct probability, above-mentioned
Process is referred to as Interference Cancellation.
Fig. 1 is the schematic diagram in correlation technique, receipt signal in the DPCCH channel of each user being reconstructed, such as Fig. 1
Shown, base station carries out de-spreading by the receipt signal in the DPCCH channel to each user, merge and decision process after, obtain
Discriminative information must be demodulated；Then the pilot frequency information in the DPCCH channel according to each user reception and the demodulation of described acquisition are adjudicated
Information, is reconstructed to receipt signal in the DPCCH channel of each user, and based on the signal after reconstruct to the user receiving
Base band data carries out parallel interference cancellation process.Fig. 2 is the rough schematic view of correlation technique reconstruction processing according to Fig. 1, such as
Shown in Fig. 2, a set of reconstruct resource is specially enjoyed to the DPCCH channel of each user, the DPCCH channel reconstruction having 512 users is accomplished by
512 sets of reconstruct resources；If each user channel species to be supported is more, need more to reconstruct resource.
However, in real system work, can't always need in most cases to be reconstructed counteracting to full user,
For example,（1）The user of system access is few or channel species is few；（2）When interfering with each other strong between user/channel, solution is reconciled
The correct user of code or channel are simultaneously few；（3）Only the correct user/channel of demodulating and decoding just can be reconstructed interference and support
Disappear, if full user/channel all demodulating and decodings are correct, also avoid the need for reconstruct and counteract.
Therefore, there is a problem of in the related reconstructing resource serious waste.

Specific embodiment
To describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the embodiment in the application and the feature in embodiment can be mutually combined.
Provide a kind of reconstruction processing method in the present embodiment, Fig. 3 is reconstruction processing side according to embodiments of the present invention
The flow chart of method, as shown in figure 3, this flow process comprises the steps：
Step S302, determines, according to the performance of interference cancellation systems, the reconstruct resource tricks that interference cancellation systems need；
Step S304, using multi-user and multi-channel share or time division multiplex a set of reconstruct resource by the way of to Interference Cancellation system
Reconstruction task in system is reconstructed.
By above-mentioned steps, after determining reconstruct resource tricks, shared using multi-user and multi-channel or the time-division utilizes
The mode of a set of reconstruct resource is reconstructed to reconstruction task, with respect to the various channels special of each user in correlation technique
For covering reconstruct resource, due to reconstruct resource tricks being determined according to systematic function it is achieved that distribution according to need reconstructs resource, in addition,
Due to not needing the reconstruct Resource Design circuit for each each channel of user, thus reduce the circuit area of chip, therefore,
Not only solve the problem wasting reconstruct resource in correlation technique, and, reach distribution according to need reconstruct resource, and reduce core
The effect of piece circuit area.
Using multi-user and multi-channel share or time division multiplex a set of reconstruct resource by the way of to the weight in interference cancellation systems

Total foundation of resource tricks is：Systematic function aggregate demand reconstructs the disposal ability of resource with single set, and for example, system needs to process
The each 2 kinds of channels of 200 users, then need to process 400 channels it is assumed that single set reconstruct resource only can process 500 channels then altogether
Need a set of reconstruct resource；Assume that single set resource can process 300 channels and then need two sets of reconstruct resources, and for example, it is contemplated that
Control channel in interference cancellation systems has different flow temporal aspects from data channel, thus can be this Interference Cancellation
The control channel of system and data channel are respectively allocated a set of reconstruct resource, certainly, also can be the control of certain 100 user completely
Channel data channel distribution processed a set of reconstruct resource, in addition the control channel data channel distribution of 100 users are another set of
Reconstruct resource；As long as following above-mentioned total foundation, determined that the mode of reconstruct resource tricks can be a lot, for specific embodiment party
Formula does not limit.
Using multi-user and multi-channel share or time division multiplex a set of reconstruct resource by the way of in interference cancellation systems
