1.一種編碼方法，其特征在于，包括：

獲取用于對(duì)K個(gè)待編碼比特進(jìn)行編碼的第一序列，所述第一序列中包含N個(gè)極化信道的序號(hào)，所述第一序列為序列Q11或表Q11所示的序列的子集，所述K為正整數(shù)，N為Polar碼的母碼長度，N＝2ⁿ，n為正整數(shù)，K≤N，N大于等于64；

從所述第一序列中選擇K個(gè)極化信道的序號(hào)；

按照所選擇的K個(gè)極化信道的序號(hào)放置所述K個(gè)待編碼比特，并對(duì)所述K個(gè)待編碼比特進(jìn)行Polar碼編碼；

其中，序列Q11為：

[0,1,2,4,8,16,32,3,5,64,9,6,17,10,18,128,12,33,65,20,256,34,24,36,7,129,66,512,11,40,68,130,19,13,48,14,72,257,21,132,35,258,26,513,80,37,25,22,136,260,264,38,514,96,67,41,144,28,69,42,516,49,74,272,160,520,288,528,192,544,70,44,131,81,50,73,15,320,133,52,23,134,384,76,137,82,56,27,97,39,259,84,138,145,261,29,43,98,515,88,140,30,146,71,262,265,161,576,45,100,640,51,148,46,75,266,273,517,104,162,53,193,152,77,164,768,268,274,518,54,83,57,521,112,135,78,289,194,85,276,522,58,168,139,99,86,60,280,89,290,529,524,196,141,101,147,176,142,530,321,31,200,90,545,292,322,532,263,149,102,105,304,296,163,92,47,267,385,546,324,208,386,150,153,165,106,55,328,536,577,548,113,154,79,269,108,578,224,166,519,552,195,270,641,523,275,580,291,59,169,560,114,277,156,87,197,116,170,61,531,525,642,281,278,526,177,293,388,91,584,769,198,172,120,201,336,62,282,143,103,178,294,93,644,202,592,323,392,297,770,107,180,151,209,284,648,94,204,298,400,608,352,325,533,155,210,305,547,300,109,184,534,537,115,167,225,326,306,772,157,656,329,110,117,212,171,776,330,226,549,538,387,308,216,416,271,279,158,337,550,672,118,332,579,540,389,173,121,553,199,784,179,228,338,312,704,390,174,554,581,393,283,122,448,353,561,203,63,340,394,527,582,556,181,295,285,232,124,205,182,643,562,286,585,299,354,211,401,185,396,344,586,645,593,535,240,206,95,327,564,800,402,356,307,301,417,213,568,832,588,186,646,404,227,896,594,418,302,649,771,360,539,111,331,214,309,188,449,217,408,609,596,551,650,229,159,420,310,541,773,610,657,333,119,600,339,218,368,652,230,391,313,450,542,334,233,555,774,175,123,658,612,341,777,220,314,424,395,673,583,355,287,183,234,125,557,660,616,342,316,241,778,563,345,452,397,403,207,674,558,785,432,357,187,236,664,624,587,780,705,126,242,565,398,346,456,358,405,303,569,244,595,189,566,676,361,706,589,215,786,647,348,419,406,464,680,801,362,590,409,570,788,597,572,219,311,708,598,601,651,421,792,802,611,602,410,231,688,653,248,369,190,364,654,659,335,480,315,221,370,613,422,425,451,614,543,235,412,343,372,775,317,222,426,453,237,559,833,804,712,834,661,808,779,617,604,433,720,816,836,347,897,243,662,454,318,675,618,898,781,376,428,665,736,567,840,625,238,359,457,399,787,591,678,434,677,349,245,458,666,620,363,127,191,782,407,436,626,571,465,681,246,707,350,599,668,790,460,249,682,573,411,803,789,709,365,440,628,689,374,423,466,793,250,371,481,574,413,603,366,468,655,900,805,615,684,710,429,794,252,373,605,848,690,713,632,482,806,427,904,414,223,663,692,835,619,472,455,796,809,714,721,837,716,864,810,606,912,722,696,377,435,817,319,621,812,484,430,838,667,488,239,378,459,622,627,437,380,818,461,496,669,679,724,841,629,351,467,438,737,251,462,442,441,469,247,683,842,738,899,670,783,849,820,728,928,791,367,901,630,685,844,633,711,253,691,824,902,686,740,850,375,444,470,483,415,485,905,795,473,634,744,852,960,865,693,797,906,715,807,474,636,694,254,717,575,913,798,811,379,697,431,607,489,866,723,486,908,718,813,476,856,839,725,698,914,752,868,819,814,439,929,490,623,671,739,916,463,843,381,497,930,821,726,961,872,492,631,729,700,443,741,845,920,382,822,851,730,498,880,742,445,471,635,932,687,903,825,500,846,745,826,732,446,962,936,475,853,867,637,907,487,695,746,828,753,854,857,504,799,255,964,909,719,477,915,638,748,944,869,491,699,754,858,478,968,383,910,815,976,870,917,727,493,873,701,931,756,860,499,731,823,922,874,918,502,933,743,760,881,494,702,921,501,876,847,992,447,733,827,934,882,937,963,747,505,855,924,734,829,965,938,884,506,749,945,966,755,859,940,830,911,871,639,888,479,946,750,969,508,861,757,970,919,875,862,758,948,977,923,972,761,877,952,495,703,935,978,883,762,503,925,878,735,993,885,939,994,980,926,764,941,967,886,831,947,507,889,984,751,942,996,971,890,509,949,973,1000,892,950,863,759,1008,510,979,953,763,974,954,879,981,982,927,995,765,956,887,985,997,986,943,891,998,766,511,988,1001,951,1002,893,975,894,1009,955,1004,1010,957,983,958,987,1012,999,1016,767,989,1003,990,1005,959,1011,1013,895,1006,1014,1017,1018,991,1020,1007,1015,1019,1021,1022,1023]
