Description

The method that time-interleaved reconciliation is time-interleaved is realized in NGB-W communication system

Technical field

The present invention relates to broadcast television communications field, particularly to one in radio and television wireless NGB-W communication of future generation System realizes the method that time-interleaved reconciliation is time-interleaved.

Background technology

Along with the fast development of World Economics culture, the demand of information service is quickly increased by mobile subscriber.Individually depend on By traditional broadcast net or tradition bi-directional communication network, the optimization transmission of mobile message business all cannot be realized.And next generation's broadcast Communication system that television network is wireless (Next Generation Broadcasting networks-Wireless, NGB-W), can be real Existing radio broadcasting and the amalgamation and coexistence of two-way communication, be to solve mobile message business datum amount quickly to increase and wireless network transmissions The effective way of contradiction between capacity constraint, because reasonability and the wide market prospect of its technology receive academia and industry The extensive concern on boundary.

NGB-W communication system traffic is mainly directed towards terrestrial transmission (transmission environment is complicated and changeable), thus it may face sternly The multi-path jamming problem of weight.In order to improve the reliability of NGB-W signal transmission, NGB-W communication system introduces time-interleaved skill Art.Time-interleaved technology, the mistake that burst generation during transmission can be compared concentration is divided the most to greatest extent Dispersion, effectively increases the length of the anti-mistake continuously of forward error correction coding (Forward Error Correction, FEC), enters One step improves communication system performance.In NGB-W communication system, the physical layer pipe that different business data flow inputs is different (Physical Layer Pipes, physical layer pipe PLP), each physical layer pipe PLP is carried out the time independently at transmitting terminal Interweaving, different physical layer pipe PLP may select different time-interleaved parameter values, after each physical layer pipe PLP data interlacing Multiplexing exports.After required physical layer pipe PLP is deinterleaved by receiving terminal the most as required, output decodes, and is wherein passed Defeated business datum.

Bit Interleaved Coded Modulation module is controlled by NGB-W communication system scheduler by signaling information so that ratio Special Interleaved Coded Modulation module completes the Interleaved Coded Modulation to each physical layer pipe PLP according to signaling information.In signaling information Physical (L1) signaling closely related with physical layer pipe PLP, it includes before L1 signaling two parts after signaling and physical layer L1. Before L1, signaling provides for signaling after physical layer L1 and receives the decode required information, and after physical layer L1, signaling provides for receiving terminal Find the information needed for physical layer pipe PLP.After physical layer L1, signaling can be further divided into configurable signaling and dynamic signaling, its In, the parameter information that L1 can configure in signaling keeps constant in a superframe, can be effectively saved signaling space；And L1 is dynamic Parameter information in signaling is equal alterable within each NGB-W frame period, arranges for parameter and provides motility.Physical layer L1 Rear signaling provides the various parameters of physical layer pipe PLP, and in the most just including each physical layer pipe PLP, transmitted data are real Existing time-interleaved required parameter information, is individually positioned in L1 and can configure in signaling territory and L1 dynamic signaling territory.NGB-W communication system Time-interleaved parameter is dynamically configured by system according to the performance requirement of the carried business of each physical layer pipe PLP, transmitting terminal Utilizing these parameter informations value deadline to interweave, receiving terminal then knows each physical layer pipe PLP time by demodulation signaling Interleave parameter, completes the deinterleaving of required physical layer pipe PLP business datum accordingly.As can be seen here, by L1 signalling time Between interleave parameter can more improve and realize the time-interleaved of each physical layer pipe PLP data neatly.

The deinterleaving method typically taked in digital communication is block interleaving and convolutional interleave.Block interleaving is also matrix ranks transposition Method, it utilizes a two dimensional memory arrays to realize.During block interleaving, data are written in column, and read by row；During deinterleaving, data are then Enter by row write, read by row.Block interleaving simple in construction, but data delay time length and also required memorizer is bigger.Convolution Interweaving is then method based on Forney, and it is realized by multiple shift register group.Port number and each channel time delay are real Two important parameter bodies of existing convolutional interleave.The quantity of the used shift register group of convolutional interleave is convolutional deinterleaver passage Number, the data cycle that the time delay on each passage the most usually differs.The work joint of input pressed by the outfan of interleaver Beating-in step is sequentially output the data on each time delay passage through time delay.Deinterleaver has the port number identical with interleaver, and Delay period on each passage is then contrary with interleaver, thus ensures that time delay is fixed end to end.

Existing broadcast communication standard uses the time-interleaved scheme differed according to respective application scenarios.DVB-T2 marks Accurate use that simple block interleaving realizes in interframe or frame time-interleaved；DVB-SH standard then defines four kinds and differs It is time-interleaved that the convolutional interleave scheme of attribute realizes differing under scene；DVB-NGH standard above ground portion considers to use frame Between convolutional interleave and intra block interweave the time-interleaved scheme of cascade, it can be in the case of not reducing order of diversity, effectively Realize long intertexture.The pluses and minuses of time-interleaved scheme in overall merit and each standard of measurement, NGB-W telecommunications system Terrestrial broadcasts portion Divide and be considered as interframe convolutional interleave and the time-interleaved scheme of intra block intertexture cascade.The time-interleaved scheme of this tandem type can It is divided into interleave unit packet, interframe convolutional interleave and intra block intertexture three phases.First, within each NGB-W frame period, will All FEC Block of input are divided into several interleave unit, interleave unit number that each FEC Block is grouped and physical layer pipe PLP is used the port number of sub-convolutional deinterleaver identical within the corresponding frame period；Secondly, interframe convolutional interleave is rolled up by many height Long-pending interleaver Parallel Implementation, each sub-convolutional deinterleaver processes a FEC Block number, by identical for size in each FEC Block Interleave unit is respectively fed in each time delay passage of corresponding sub-convolutional deinterleaver successively, and different delay passage arranges different delay ginseng Number, and with NGB-W frame as ultimate unit, to realize interframe convolutional interleave；Finally, within each NGB-W frame period, each height is rolled up All interleave unit of long-pending interleaver output carry out unified intra block and interweave.

When realizing interframe convolutional interleave, the sub-convolutional deinterleaver number used in each NGB-W frame and physical layer pipe PLP Within each NGB-W frame period, input data rate is relevant.If physical layer pipe PLP input data rate is constant, i.e. often The FEC Block constant number that in one NGB-W frame period, physical layer pipe PLP is carried, then physical layer pipe PLP uses parallel The quantity of sub-convolutional deinterleaver is also constant, for the FEC Block number of input in each NGB-W frame period.If physical layer pipe PLP data rate is variable, the FEC Block variable amounts that i.e. in each NGB-W frame period, physical layer pipe PLP is carried, then thing The quantity of the sub-convolutional deinterleaver that reason layer pipeline PLP uses parallel is also variable.When data rate rises, i.e. physical layer pipe PLP is time within the NGB-W frame period, FEC Block number starts to increase, the sub-convolutional deinterleaver number also phase that physical layer pipe PLP uses parallel Should increase on ground.Now, quantity and the FEC in the corresponding NGB-W frame period of sub-convolutional deinterleaver are used in each NGB-W frame period Number of blocks is identical.And when FEC Block number reduces within the NGB-W frame period for data rate decline, i.e. physical layer pipe PLP, physics Layer pipeline PLP use within each NGB-W frame period the quantity of sub-convolutional deinterleaver no longer to physical layer pipe PLP corresponding The FEC Block quantity actually entered in the NGB-W frame period is identical.At this time, it may be necessary to fill appropriate virtual within the NGB-W frame period FEC Block so that after filling, the FEC Block number in each frame is identical with the sub-convolutional deinterleaver number used in the corresponding NGB-W frame period. If the effective interleave unit deposited in shift register on certain sub-convolutional deinterleaver each time delay passage has been output, then This sub-convolutional deinterleaver can be abandoned, stop filling virtual FEC Block simultaneously.

Cascading in time-interleaved scheme from DVB-NGH standard uses uniform interframe convolutional interleave different, NGB-W standard level Join time-interleaved scheme and be considered as time delay and the port number of interframe convolutional interleave heterogeneous, i.e. each passage of convolutional deinterleaver It it is no longer linear relationship.Therefore time-interleaved parameter cannot be completely suitable for NGB-W standard in DVB-NGH standard.DVB-T2 Standard or DVB-SH standard are only with single interleaving scheme, therefore its interleave parameter information transmitted in the signaling also cannot be fitted For NGB-W standard.

$N_{\mathrm{DUMMY}\_\mathrm{IU}}=\left\{\begin{array}{cc}0& N_{\mathrm{CI}}=N_{\mathrm{FEC}}\left(i\right)\\ N_{\mathrm{CI}}-N_{\mathrm{FEC}}\left(i\right)& N_{\mathrm{CI}}\≠N_{\mathrm{FEC}}\left(i\right)\end{array}\right.\stackrel{N_{\mathrm{CT}}=3}{\→}$

$N_{\mathrm{DUMMY}\_\mathrm{IU}}=\left[\begin{array}{cc}0& N_{\mathrm{FEC}}\left(i\right)=3\\ 3-N_{\mathrm{FEC}}\left(i\right)& N_{\mathrm{FEC}}\left(i\right)\≠3\end{array}\right]$

k=i*N_CI+N_FEC(i)+l N_CI≠N_FEC(i) and l ∈ (1 ..., N_CI-N_FEC(i))

$\stackrel{N_{\mathrm{CI}}=3}{\→}k=i*3+N_{\mathrm{FEC}}\left(i\right)+l$ N_FEC(i) ≠ 3 and l ∈ (1 ..., 3-N_FEC(i))’

In this way, 4 passage outputs of each frame (frame 1 to frame 5) interior 3 sub-convolutional deinterleaver it are calculated successively In number N of all dwell vessel original states_{DUMMY_IU}And residing line number k(such as Fig. 4), and by the beginning of the depositor in these 5 frames Beginning state is deleted.
