And use this first decoder module to be decoded this first kind coding data traffic stream.
Step S104: when the type of this coding data traffic stream is Equations of The Second Kind, by this Equations of The Second Kind coded number
Inputting in this second decoder module (that is, low error rate requires decoder module) according to Business Stream, using should
This Equations of The Second Kind coding data traffic stream is decoded by the second decoder module.
Additionally, when the hybrid coding data service stream that this coding data traffic stream is the first kind and Equations of The Second Kind,

Specifically, with reference to Fig. 3, Fig. 3 is the reality describing coding/decoding method according to a first embodiment of the present invention
Existing block diagram.In the figure, two data buffer storages 1 and 2 are used to carry out data input, this data buffer storage 1
Using Pingpang Memory mode with 2, alternately storing, each caching all can serve data to
Two passages below.In the figure, the data stream packets of input includes three kinds of situations:
1. when 1. the data stream of input include the first kind and Equations of The Second Kind coding data traffic stream, by data stream
1. first kind coding data traffic stream input the first decoder module in is (for example, based on MAX-log-map
The Turbo code decoder module of decoding algorithm) in, and by data stream 1. in Equations of The Second Kind coded data
Business Stream inputs the second decoder module (for example, Turbo code decoder mould based on SOVA decoding algorithm
Block) in.Therefore, it can to decode in the first decoder module simultaneously first kind coding data traffic stream and
In second decoder module decode Equations of The Second Kind coding data traffic stream, it is possible to achieve synchronization high efficiency parallel
Decoding.
2., when 2. the data stream of input only include Equations of The Second Kind coding data traffic stream, 2. data stream inputted
In second decoder module (for example, the Turbo code decoder module based on SOVA decoding algorithm).Cause
This, is because passing through two-stage RAM buffered data so that when decoder decodes, first RAM simultaneously
Data can be read in, save the time of single reading evidence.
3., when 3. the data stream of input only include first kind coding data traffic stream, 3. data stream inputted
First decoder module (for example, the Turbo code decoder module based on MAX-log-map decoding algorithm)
In.Consequently, because pass through two-stage RAM buffered data so that when decoder decodes, simultaneously first
Individual RAM can read in data, saves the time of single reading evidence.
Additionally, when the type of this coding data traffic stream is the first kind (that is, the coding that high bit-error requires
Data service stream) when, determining the pattern of this first kind coding data traffic stream, described pattern refers to this coding
The mobile communication standard of data service stream.It is to say, the coding data traffic that high bit-error is required
Stream, can also be determined by the pattern of coding data traffic stream, i.e. the movement of coding data traffic stream is led to
Beacon is accurate, provides different Turbo code decoder module.For example, when the requirement of this high bit-error
When coding data traffic stream is the data stream based on LTE standard, use based on LTE standard interleaver/
Deinterleaver and two RSC decoders are decoded.When the coding data traffic stream that this high bit-error requires
When being the data stream based on TD-SCDMA standard, use based on TD-SCDMA standard interleaver/
Deinterleaver and two RSC decoders are decoded.
To this end, this first decoder module can include based on the first decoding algorithm (for example, MAX-log-map
Decoding algorithm) one or more decoding sub-module, such as decoding sub-module, the pin for LTE standard
Decoding sub-module, the submodule etc. for WCDMA standard to TD-SCDMA standard.According to this
The pattern of first kind coding data traffic stream, i.e. be based on which kind of mobile communication standard, selects corresponding
The first kind coding data traffic stream of input is decoded by decoding sub-module independently.This mobile communication mark
Standard includes the mobile communication standard for 2G signal, including GPRS and GSM, described second move logical
Beacon is accurate for the mobile communication standard for 3G signal, including TD-SCDMA, CDMA2000,
WCDMA and WiMAX, and described 3rd mobile communication standard is for for the mobile communication of 4G signal
Standard, including LTE and TD-LTE.Further, it is also possible to according to the development of mobile communication, responsively carry
For the decoding sub-module for the later mobile communication standard occurring.
It is to say, each decoding sub-module intactly includes one group of friendship for specific mobile communication standard
Knitting/deinterleave unit and two RSC decoders, this group interleaving/deinterleaving unit includes an interleave unit
Deinterleave unit with one.Therefore, the coded number that each decoding sub-module can independently to a kind of pattern
It is decoded according to Business Stream.

Knit unit, and carry out at least two RSC decoder being multiplexed the first kind coded data industry to input
Business stream is decoded.For example, when the encoded data stream that the encoded data stream of input is LTE standard, connect
It is common to one group of interleaving/deinterleaving unit of LTE standard and two RSC decoders 1 and 2, simultaneously switch off
For one group of interleaving/deinterleaving unit of TD-SCDMA standard, therefore, it can to input based on LTE
The encoded data stream of standard is decoded.
Additionally, when input data are Equations of The Second Kind coding data traffic stream (that is, the codings that low error rate requires
Data service stream) when, this second decoder module can include based on the second decoding algorithm (for example, based on
SOVA decoding algorithm) one or more decoding sub-module, wherein each decoding sub-module is right independently

During the voice data traffic stream that low error rate requires, this coding data traffic stream can be inputted a decoding
Submodule, is decoded to the voice data traffic stream of this input wherein independently.
Furthermore it is also possible to provide control module, this control in the decoder device using this coding/decoding method
Module stores decoding parametric list, for example, is iterated the number of times of decoding.
Therefore, when this first kind coding data traffic stream being decoded by this first decoder module,
According to the length of each packet in this first kind coding data traffic stream, from this decoding parametric list
Select corresponding decoding parametric, thus according to the decoding parametric selecting, each packet is decoded.
Specifically, in the case of 188 kinds of different types of data packets, true according to different grouping length
Definite decoding characteristic, under a usual Parameter Conditions, uses different Operation Measures to every kind of packet decoding,
Such as the number of times difference of iterative decoding, these differences are all through the data tested of practice, compare fixing
The iterative decoding of pattern is more efficient.In addition, this decoding parametric list can also make according to the different external worlds
Select by scene.
Because the first decoder module is higher than the second decoder module, therefore, this first solution for bit error rate requirement
Code module requires the power higher than the second decoder module.
Additionally, at decoded output, the data that decoding terminates first send into FIFO caching, and FIFO depth can
To be 8bit, 16bit, 32bit etc., can according to lower DBMS form it needs to be determined that.Then again with 8bit,
The mode of 16bit or 32bit exports to subordinate's code block cascade module together, it is to avoid the transmission of 1bit serial
Mode.The FIFO for example using the degree of depth to be 8bit, it is possible to make subordinate's code block cascade module at first 7
Power-off in clock cycle, opens the 8th clock cycle and receives the wide data of a 8bit, then can
To save the power consumption close to 7/8.FIFO is i.e. utilized to provide convenience for the economize on electricity of subordinate's module.
