Research On The Design Of Punctured Complementary Sequence Pair Sets With Zero Correlation Zone

Sequence design plays a key role in the field of wireless communication.The conventional sequence design mainly includes the perfect binary sequence pair.But they are suffered from the limitation of number.The theory of sequence pairs extends the existence space of the signals.The zero correlation zone(ZCZ)sequence pairs and sequence pair sets are significant for reducing code division multiple access(CDMA)with multi-access interference and multipath interference.This paper mainly studies the construction of the ZCZ punctured complementary sequence pair sets.First of all,this paper puts forward two construction methods of the aperiodic ZCZ punctured complementary sequence pair sets.Based on the perfect punctured binary sequence pairs and it shifting.And the aperiodic ZCZ punctured complementary sequence pair sets can be obtained by two different interleaving technology with the punctured orthogonal matrix pairs and the orthogonal matrix.This kind of sequence pair sets achieving the theoretical bound was constructed by flexible choosing different parameters.This paper defines four types of good correlation aperiodic punctured binary sequence pairs.And writes the computer program search results..These results make up the gap punctured sequence pairs in aperiodic sequence.Secondly,this paper puts forward construction methods of the 8-QAM+ and quaternary periodic ZCZ punctured complementary sequence pair sets.Based on the perfect binary sequence pairs and the orthogonal matrix and it row shifting.Punctured orthogonal matrix pairs and the orthogonal matrix with larger capacity are achieved.Subsequences the binary ZCZ punctured complementary sequence pair sets are presented by interleaving and iterative technique.The 8-QAM+ and quaternary periodic ZCZ punctured complementary sequence pair sets are constructed with using 8-QAM constellation and inverse Gray mapping.These sequence pair sets are widened in capacity and sequence number.Finally,this paper puts forward construction methods of the L/ZCZ punctured complementary sequences pair sets.The ZCZ punctured sequence pair sets with the flexible number of subsequences are constructed based on the perfect punctured sequence pairs by shifting and interleaving technique.Then this sequence pair sets and the orthogonal matrix with circular multiplication achieve the method of the ZCZ punctured complementary sequence pair sets.The LCZ punctured complementary sequence pair sets with the flexible number of subsequences are constructed based on the pseudorandom punctured binary sequence pairs.The method enriched the construction of the L/ZCZ punctured sequence pair sets.
