Below in conjunction with accompanying drawing the embodiment of the invention is done description further.
Embodiment one
In embodiment one; Code multiplexing process with the HS-DSCH that adopts the 16QAM modulation is an example; In this process, adopt the interleaver of two same sizes that input bit is interweaved, these two interleavers are R2 * C2=32 * 30; Input bit is divided into the two-way bit sequence, bit u in twos between these two interleavers

In embodiment one; For these two interleavers dispose the different patterns that interweaves respectively, wherein, the pattern that respectively interweaves is an example only the initial position of input bit sequence is defined into the target location by row; In concrete the realization; Interleaver adopts, and the pattern that interweaves can be defined into the initial position of input bit sequence the target location or by cell the initial position of input bit sequence is defined into the target location by row by row, and in embodiment one, the pattern that interweaves of first interleaver is as shown in table 1:
Table 1
| Columns C2 | Interweave between row pattern P2 (0), P2 (1) ..., P2 (C2-1) > |
| 30 | <0，20，10，5，15，25，3，13，23，8，18，28，1，11，21， 6，16，26，4，14，24，19，9，29，12，2，7，22，27，17> |

P, 2, u
P, 3..., u
P, UY from the 0th row, the 0th row
P, 1Beginning writes matrix R2 * C2 line by line;
This matrix column from left to right be numbered 0,1,2 ..., C2-1; The row of this matrix is numbered 0,1,2 from top to bottom ..., R2-1.Matrix R2 * the C2 that writes completion is:
Wherein, y

The interleaving process that carries out in the interleaving process that in second interleaver, carries out and first interleaver is identical, only is the pattern difference that interweaves that accordings to.Behind second interleaved sequence of first interleaved sequence that obtains the output of first interleaver and the output of second interleaver, first interleaved sequence and second interleaved sequence are combined according to the order of distributing in twos.
Because in the present embodiment, only require that first interleaver is different with the pattern that interweaves that second interleaver adopts, therefore; In two patterns that interweave; (for embodiment one, promptly for the corresponding target location different portions of initial position of exchange row in two patterns that interweave, identical two bits of input sequence are respectively through after the interweaving of two interleavers for the target location different portions of the identical data of definition initial position; Can produce the gain that interweaves); Identical two bits of input sequence through after the interweaving of two interleavers, can produce the gain that interweaves respectively, and promptly variation has taken place the distance of these two bits.For example, in the pattern that interweaves that first interleaver adopts, initial position is that the target location of 0 row still is 0; And in the pattern that interweaves that second interleaver adopts, initial position is that the target location of 0 row is 30, and is visible; When the bit that the bit and second interleaver of the output of first interleaver are exported combines; The initial position of two interleavers output be 0 be listed in interweave after, variation has taken place in distance, has produced the gain that interweaves.
In the present embodiment; The pattern that interweaves that two interleavers are adopted does not need concrete qualification; But, in order all to have the gain that interweaves between the bit that makes two interleaver outputs, in these two the different patterns that interweave; Should guarantee the row that each initial position is identical, its target location is all inequality as far as possible.
And because the pattern that interweaves that two interleavers are adopted does not have concrete the qualification; Therefore; The storage overhead that brings in order to reduce storage to interweave pattern; In the present embodiment, can only preserve the pattern that interweaves that an interleaver adopts, and be used as the pattern that interweaves that another interleaver adopts with the distortion of this pattern that interweaves.In embodiment one; The pattern that interweaves that first interleaver adopts is the pattern that interweaves shown in the table 1; And the pattern that interweaves that second interleaver adopts can obtain according to the distortion of the pattern that interweaves shown in the table 1; The mode of carrying out this distortion has a lot, and the pattern that interweaves shown in several kinds of mode his-and-hers watches 1 below for example adopting is out of shape:
Mode one
The pattern that interweaves of second interleaver is the backward of the pattern that interweaves of first interleaver, and then the pattern that interweaves shown in the table 1 being carried out corresponding deformation, to obtain the pattern that interweaves of second interleaver as shown in table 2:
Table 2
| Columns C2 | Interweave between row pattern P2 (0), P2 (1) ..., P2 (C2-1) > |
| 30 | <17，27，22，7，2，12，29，9，19，24，14，4，26，16，6 21，11，1，28，18，8，23，13，3，25，15，5，10，20，0> |
Mode two
Generating the interweaving during pattern of second interleaver, earlier the pattern that interweaves of first interleaver is being carried out backward and arrange, the first half and latter half exchange of the pattern that interweaves after again backward being arranged, the pattern that interweaves of second interleaver that then obtains is as shown in table 3:
Table 3
| Columns C2 | Interweave between row pattern P2 (0), P2 (1) ..., P2 (C2-1) > |
| 30 | <21，11，1，28，18，8，23，13，3，25，15，5，10，20，0 17，27，22，7，2，12，29，9，19，24，14，4，26，16，6> |
Mode three
The pattern that interweaves of second interleaver is that first half and the latter half of the pattern that interweaves of first interleaver exchanges, and then the pattern that interweaves shown in the table 1 being carried out corresponding deformation, to obtain the pattern that interweaves of second interleaver as shown in table 4:
Table 4
| Columns C2 | Interweave between row pattern P2 (0), P2 (1) ..., P2 (C2-1) > |
| 30 | <6，16，26，4，14，24，19，9，29，12，2，7，22，27，17 0，20，10，5，15，25，3，13，23，8，18，28，1，11，21> |
It is thus clear that; Because the pattern that interweaves that obtains according to above-mentioned variety of way is on the basis of the pattern that interweaves shown in the table 1, to obtain through simply handling to be out of shape; Do not need other buffer memory to store this pattern that interweaves, saved storage overhead, and; Because this deformation process is very simple, can't increase the complexity of interleaving treatment because of this deformation process.
When concrete the realization, can not be out of shape another pattern that interweaves of generation yet, but directly preserve two patterns that interweave according to the pattern of storing that interweaves, these two patterns that interweave can dispose as required, as long as guarantee that two patterns that interweave are different.For example, the pattern that interweaves that makes second interleaver is a random alignment of the pattern that interweaves of first interleaver, i.e. 1～30 random alignment, but should guarantee that two patterns that interweave are inequality.Under the situation of two patterns that interweave of direct preservation, need to increase certain storage overhead, but owing to the required memory space of intersection chart sample body is little, therefore, the storage overhead of its increase can not cause the bigger burden of system yet.
Embodiment two
In embodiment two; Code multiplexing process with the HS-DSCH that adopts the 64QAM modulation is an example; In this process, adopt the interleaver of three same sizes that input bit is interweaved, these three interleavers are R2 * C2=32 * 30; Input bit is divided into three tunnel sequences, bit u between these three interleavers
P, kAnd u
P, k+1Send to first interleaver, bit u
P, k+2And u
P, k+3Send to second interleaver, bit u
P, k+4And u
P, k+5Send to the 3rd interleaver, each road sequence interweaves respectively, and the output bit sequence of three interleavers combines according to the order of distributing again, is specially bit v
P, kAnd v
P, k+1From the output of first interleaver, bit v
P, k+2And v
P, k+3From the output of second interleaver, bit v
P, k+4And v
P, k+5From the output of first interleaver, later bit sequence by that analogy.
In embodiment two, same, as long as guarantee that the pattern that interweaves of each interleaver employing is inequality; So; For the corresponding target location different portions of the initial position of exchange row in any two patterns that interweave in three patterns that interweave, identical two bits of input sequence through after the interweaving of two interleavers, can produce the gain that interweaves respectively; Situation compared with each interleaver employing same interlace pattern can obtain the effect that better interweaves.
Thus it is clear that, when adopting two or more interleavers to interweave,, just can obtain the effect that better interweaves as long as adopt the mutually different pattern that interweaves.In addition, if guarantee all to exist between each bit the gain that interweaves, need guarantee that then data definition that should be as far as possible that initial position is identical is to different target locations in this two or more different pattern that interweaves.
Embodiment three
In embodiment three; E-DCH to adopt the 4PAM modulation is an example; In this process; Adopting the identical size of two-way is the interleaver of R2 * 30, wherein the smallest positive integral of R2 for satisfying
.Input bit gets into the two-way interleaver successively.u
P, kGet into first via interleaver, u
P, k+1Get into the second road interleaver.Through after the interweaving of two-way interleaver, read bit from two interleavers successively and export, be i.e. v
P, kFrom first interleaver, v
P, k+1From second interleaver, wherein k mod 2=1.Such as a length is 60 bit sequence, and its index is followed successively by: 1,2 ..., 60, then wherein index is { 1,3,5,7,9,11,13,15,17,19,21,23; 25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55; 57, the sequence of 59} gets into first interleaver, and index is { 2,4,6,8,10,12,14,16,18,20,22,24,26,28; 30,32,34,36,38,40,42,44,46,48,50,52,54,56,58, the bit of 60} gets into the second road interleaver.
If two interleavers adopt same interlace patterns as shown in table 1, then through after the interweaving of first via interleaver, the corresponding index of output bit is: { 1,41,21,11,31,51,7,27,47,17,37,57,3,23,43,13; 33,53,9,29,49,39,19,59,25,5,15,45,55,35}, through after the interweaving of the second road interleaver, the corresponding index of output bit is: { 2,42,22; 12,32,52,8,28,48,18,38,58,4,24,44,14,34,54,10,30,50; 40,20,60,26,6,16,46,56,36}, then, the index of the bit sequence that obtains after the output bit of two interleavers combined is: { 1,2,41,42,21,22,11,12; 31,32,51,52,7,8,27,28,47,48,17,18,37,38,57,58,3,4; 23,24,43,44,13,14,33,34,53,54,9,10,29,30,49,50,39; 40,19,20,59,60,25,26,5,6,15,16,45,46,55,56,35,36}.
It is thus clear that through after the interweaving of two interleavers, the list entries index is the gain that do not interweave between the input bit of k and k+1, that is, the list entries index is that 1,2 bit, list entries index are the gain that all do not interweave of 41,42 ratio top grade.
And if make first interleaver adopt the pattern that interweaves as shown in table 1, and second interleaver adopts the pattern that interweaves as shown in table 2, and makes that aforesaid length is that the index of 60 bit sequence is that the bit of odd number is imported first interleaver, then the index of the output bit sequence of first interleaver is { 1,41,21,11,31,51,7,27; 47,17,37,57,3,23,43,13,33,53,9; 29,49,39,19,59,25,5,15,45,55,35}; And this length is the index of 60 bit sequence is that the bit of even number is imported second interleaver, and then the index of the output bit sequence of second interleaver is { 36,56,46,16,6,26,60,20,40,50; 30,10,54,34,14,44,24,4,58,38; 18,48,28,8,52,32,12,22,42,2}.The index of the bit sequence that then, obtains after the output bit of two interleavers is combined is: { 1,36,41,56,21,46,11,16,31,6,51,26,7,60,27; 20,47,40,17,50,37,30,57,10,3,54,23,34,43,14; 13,44,33,24,53,4,9,58,29,38,49,18,39,48,19; 28,59,8,25,52,5,32,15,12,45,22,55,42,35,2}.
It is thus clear that two interleavers are interweaving during pattern shown in employing table 1 and the table 2 respectively, the bit that index was adjacent when each was imported has all interweaved out, can obtain bigger the interweave gain and the effect that better interweaves.When concrete the realization, as long as make two interleavers adopt the different patterns that interweaves respectively.
